How the penis disappeared from the sex toy

You’ve seen what a penis looks like. Sure, there are variables that make each one a little different—the world is beautiful that way—but, generally speaking, they all fit a certain mold.

As the male sexual organ, the penis was designed to transport sperm from one body into another. As an added feature, the penis can also summon orgasm in a female partner during this process. But we know this isn’t always the case. While a healthy male organ works pretty well for its intended reproductive purpose, there are some design flaws in terms of maximizing female pleasure.

LILY 2So what if you could redesign the penis, make it a little bit better? Which pieces would you change, and which would you keep? Erasing the need for reproductive functionality, would you scrap the whole thing and start from scratch? In the end, would this magic device—capable of bringing women waves of pleasure—even resemble the penis in its current human form?

Welcome to the world of modern-day vibrators, a place largely devoid of the original pleasure device.

As sex toys have become increasingly sleek and modern—taking cues from the minimalistic designs of like Apple and Ikea—one clear trend has emerged: They no longer look like human penises. In fact, they no longer look human at all—which, according to designers, entrepreneurs, and sex therapists alike, is a very good thing.

Kitschy and grotesque

The first time the American public saw a non-human organ used to stimulate sexual arousal was in the early porn films of the 1920s. Over the previous few decades, small home appliances marketed under the guise of medical necessity (to cure the female ailment of “hysteria“) had become commonplace—kind of like how we now see “personal massagers” advertised in Brookstone. But in the new black-and-white pornos of the ’20s, audiences saw these appliances used for very non-medical purposes.

zini-deux-293x300And once the public was confronted with the idea that these devices could be used strictly for pleasure, the products disappeared from women’s magazines and reputable store shelves.

Vibrators made a second coming about 30 years later, during the sexual revolution of the 1960s. But even though Americans were talking about sexuality more openly than ever before, we still weren’t totally cool with the idea of incorporating these objects in our sex lives. In response, early industry leaders made them as outlandish as possible: Rotating glitter-dicks, two shafts emerging from one testicle-shaped base, rubber duckies that secretly vibrated. We displaced the awkwardness of using machines as sexual aids by turning these aids into novelty objects, or toys.

But there was a big problem with this approach. Since the products were advertised as “novelties,” not health aids, they were held to lower standards than medical devices and other things we put inside our bodies. The cheap toys were unsafe, ugly, and ineffective. And not at all sexy.

“I don’t think anyone has ever said, ‘I want a vibrator that looks like a bunny rabbit and a penis all smashed together,’” Ti Chang, the female co-founder of sex toy and jewelry design company Crave, told me. “I think the sex toy industry has really had a lot of male voices—it’s been men designing products for women, so it tends to be very male anatomy centric. Like, ‘Oh, it’s sex, she wants a big cock, so we’ll just make lots of different colors of cocks, and to make this really silly, we’ll put a little rabbit on it.’”

Companies like Doc Johnson—a leading novelty company for decades, notorious for its line of Zini DonutRealistic Cocks—offer a good example of the “she wants a big cock” mentality that dominated the industry during the late-20th century. Robert Rheaume, the president of high-end sex toy company JimmyJane, charmingly described these hyper-realistic dildos as the kind of severed penis you’d get if “there was an Orc from Lord of the Rings walking around, and they cut his penis off.”

He also argued, by nature of them being just so grotesque, they’re not very sex-positive. He put it to me this way: “Let’s say you and I are well into our sexual relationship, and I pull out this giant, Doc Johnson, 15-inch cock,” Rheaume said. “You might be like, WOAH, where’s that going? Get out of my apartment right now, I’m leaving—call me a taxi, call an Uber. It’s just intimidating and scary for some people.”

Kitschy, intimidating, grotesque—all are terms you could use to describe the sex toy market up until the early 2000s. The poor designs, cheap rubbers and plastics, and incredibly dick-centric domain of products presented itself as an untapped valley of junk, just waiting for a messiah. This is what Ethan Imboden, the founder of JimmyJane, realized upon walking into an Adult Novelty Manufacturers Expo a little more than a decade ago.

“As soon as I saw past the fact that in front of me happened to be two penises fused together at the base, I realized that I was looking at the only category of consumer product that had yet to be touched by design,” Imboden said in his 2012 Atlantic profile. Coming from an industrial design background, and lacking the desire to manufacture what he saw as landfill products, he left his job designing everyday consumer products to launch JimmyJane—a sex toy company that would put safety, design, and sex-positivity first. Around this time, a small, luxury intimate toy company in Sweden called LELO started doing the exact same thing.

post-phalic 01The kitschy sex toy industry was primed for a big change, and companies like JimmyJane and LELO were ready to usher it in.

Disrupting the dick

Skeuomorphism is a concept in technological design that describes our tendency to retain tactile aspects of the physical world as we move more of our lives onto screens. At Apple, for example, skeuomorphic design was thought to ease the transition from the real to the virtual. Turning a page on your Mac or iPhone would closely resemble turning a page in a real notebook, paper sounds included. If you can recreate the physical aspects of a very familiar, tactile world in the flat, virtual reality of an operating system, designers have long believed, maybe more people will feel comfortable using the product.

In sex toy design, this has translated into manufacturing dismembered penises and inventing crevices meant to resemble human vaginas and mouths. But why—if women and couples are looking for something more than their own, very real human parts—would they want a plastic knock-off of those same parts in bed? Just as some people argue that retaining archaic, physical traits of notepads on our iPhones is unnecessary, companies like JimmyJane and LELO saw retaining the original design of human organs as unnecessary and outdated.

Of course, there will probably always be a market for straight-up dildos—which are different from vibrators—and which, by nature of their intended internal purpose, must resemble a human penis. But female-oriented vibrators allow more room for innovation.

With this in mind, JimmyJane and LELO’s emphasis on design, coupled with major tech advances of the early 2000s, allowed these pioneering sex companies to essentially reinvent the penis. “Technology drives the industry—it’s tech, tech, tech,” Patti Britton, a clinical sexologist in southern California, told me. “Everyone’s going for the faster, the most options for control, as well as these really unusual and really sophisticated designs.”post-phalic 02

Those sophisticated designs are now pretty commonplace, and they look nothing like human parts. The design shift comes as a result of technological advances, yes, but also reflects a pretty significant ideological shift. Vaginal penetration, as we now know, isn’t necessarily the key to female orgasm, and penises aren’t naturally shaped to stimulate the elusive G-spot. Skeuomorphism started disappearing from the industry, and the dick was reinvented—and ultimately displaced.

Luxury investments

When sex toys start looking less like severed organs, it gets easier for consumers to take them seriously. And when consumers start to take them seriously, it opens up room for a luxury class of sex toys—something that LELO and JimmyJane, especially, have capitalized on. Most of LELO’s products start at more than $120, though the company also boasts a 24-karat gold plated vibrator for $15,000. As Steve Thomson, LELO’s global marketing manager, told me, creating toys that last a lifetime, like a nice espresso maker or television, is “a way of challenging assumptions about the sex toy market as a whole.”

“There’s always going to be a place for novelty goods and phallic-shaped items,” Thomson said. “But I don’t believe that’s the future of sex toys in any way. People are moving away from the assumption that it’s purely a substitute for a partner.”

post-phalic 03To Thomson, as well as industry leaders at JimmyJane, Crave, and the numerous other companies that have joined the modern sex toy craze, the future of sex toys is in making objects that fit easily into a consumer’s everyday life. That’s why, as technology improves, we see things like app-controlled panty vibes and vibrators equipped with memory that will store your favorite sexual patterns.

Along with loosening cultural values around discussing sex—almost everyone I interviewed cited the Fifty Shades of Grey franchise as a major breakthrough—the shift in toy design has transformed the industry from a $1.3 billion a year industry to a $15 billion a year industry in revenue alone. “If it’s okay for the modern mom to have dialogue about Fifty Shades of Grey, sexuality and masturbation, I think it gives us complete permission to have these conversations and to make these products available,” Rheaume said.

He’s not wrong. Research shows that not only are more women using toys, they’re owning up to using more toys. Consumers are literally taking their orgasms into their own hands, and they’re commonly paying upwards of $150 to do so. Is it worth it to buy a vibrator that costs a bit more than something you might find at your neighborhood adult novelty shop if it means it’ll last longer and isn’t toxic to your body? Absolutely.

But not everyone can afford it, and while some products come with a money-back, orgasm guarantee—they don’t always work as advertised. Has design for the sake of being beautiful, and innovation for the sake of being advanced, displaced the actual functionality of the vibrator?

That’s what was bothering Janet Lieberman, a mechanical engineering grad from MIT and enthusiastic sex toy user. Facing repeated disappointment in the toys she bought, Lieberman realized she was in a unique position to utilize her expertise to make things better. The technology was good, but she saw it going in the wrong direction. There was a sort of machismo attitude slipping into products designed for women—who cares if your device can track your orgasms, give you Bluetooth feedback, and looks like modern art if it doesnt work?

Now, as co-founder and lead engineer for the New York-based sex toy company Dame, she’s ushering in the newest wave—and quite likely the future—of sex toy design.

Women come first

One of the big problems with the sex toy industry is how male-driven and controlled it’s been throughout most of its history. Sure, the men at LELO and JimmyJane have women’s desires in mind—both Thomson and Rheaume told me about the extensive research measures their companies take when designing new products. JimmyJane, for example, relied on data about average labia size from the renowned Kinsey Institute when creating its new Form 5 vibrator, which is designed to simultaneously stimulate a woman’s labia and clitoris.

And to make sure the products hitting the market are truly effective, the leading companies also rely on demo communities—women who test new prototypes and provide detailed feedback. But, as Lieberman argues, there’s a difference between running a product by a demo audience and having a woman—the target consumer of the product—involved each step of the way.

And so, it’s becoming increasingly common to see women-run sex toy companies, or to see women involved in the design and engineering process, according to industry insiders. “If they’re products for women, you kind of want women everywhere in the process so they’re making the right priorities,” Lieberman told me.

A female designer and engineer, for example, might know right off the bat whether something is going to work. It’s not that men don’t take all the important components into consideration—after all, some of these products are used mutually between partners—it’s just that women are more likely to understand the various nuances in their own anatomies, and take those into consideration in the engineering process.

While enabling sex toys to track activity and communicate long distance via the internet—both features on the newest models—is cool, Lieberman and Crave’s Chang both stressed a personal mission to deliver what sex toys have long promised: really fantastic orgasms.

“Having an orgasm is like a birth right, you should have it!” Chang said, in a sentiment famously voiced by Nicki Minaj and, more recently, Amy Schumer. In her process at Crave—which steers clear of trying to mimic anything anatomical—function always comes first.

Lieberman and her business partner, Alex Fine, took a similar approach when building Dame’s first product, a couple’s vibe called Eva. “I wouldn’t say that one of our primary goals in designing this was that we wanted it to be beautiful,” Lieberman said of the device, which resembles a futuristic beetle. “We wanted it to be accessible, but we put function ahead of form.”

They also wanted to make sure the cost wasn’t prohibitive—a sex toy that’s too expensive can actually detract from sex, she argues. Eva sells for $105, a price-point Lieberman attributes mainly to the device’s high-quality silicone and the rigorous research and design process that went into it. Lieberman likens the Eva to a pair of really good headphones: You can hear the music, it sounds incredible, but you aren’t super aware of the fact that there are two small speakers in your ears.

Lieberman acknowledges that before sex toy designers could think about getting back to the core purpose of the industry, consumers needed to be introduced to beautiful, high-end luxury products. But the next wave of sex toys will likely follow her function-over-form philosophy—and encourage an even bigger audience to come.<

So, are we moving toward a world where penises, and human sex organs, are obsolete? Of course not. We’re just moving toward one where we can do better than what the average human body has to offer. As Patti Britton, a certifiable expert in all things sex, put it, there will always be an element of humanity that can’t be captured by even the most elaborate of sex toys.

“We’re still human beings—we’re skin and bone and flesh and energy,” Britton told me. “So far we really haven’t matched that one in the lab, we may one day. But I think, overall, humans will want to be with humans. That’s how we’re wired.”

I Can’t Believe People Tell Sex Workers to “Go to the Police” If They’ve Been Raped

A Few Thoughts About Stoya, James Deen, and the Rape Allegations Made on Social Media

by Mistress Matisse

deen

The law does not give a shit about sex workers. Neither do many people on Twitter.

On November 28, writer, director, and porn actress Stoya fired off two tweets that would upend the porn world.

@Stoya: “That thing where you log in to the internet for a second and see people idolizing the guy who raped you as a feminist. That thing sucks… James Deen held me down and fucked me while I said no, stop, used my safeword. I just can’t nod and smile when people bring him up anymore.”

Stoya was talking about her former partner, James Deen—the adult-video-industry icon, he of the boyish good looks and crossover media fame, whose swooning female fan base dubbed him “the feminist porn star.”

Deen was silent for a day and then posted to Twitter: “There have been some egregious claims made against me… I want to assure my friends, fans, and colleagues that these allegations are both false and defamatory… I respect women and I know and respect limits both professionally and privately.” He then went silent until earlier this week, when he gave an exclusive interview to the Daily Beast denying all allegations. He has not replied to a request for comment from The Stranger.

I believe Stoya. Unpleasant stories about Deen have circulated in the sex-work community since well before they were a couple, and in the days following her tweets, nine other women also came forward to say that Deen has assaulted them. One of the women, Joanna Angel, was in a relationship with him for six years. Their stories don’t sound like descriptions of misunderstandings or moments of bad judgement. They sound like persistently abusive behavior, dating back nearly 10 years in Deen’s life. I believe all of them.

However, one development of all this did pleasantly surprise me: Major porn companies responded swiftly to the womens’ allegations. Shortly after the allegations began coming out, major porn studios Kink.com and Evil Angel announced they would no longer work with Deen, effective immediately. Other adult businesses that had connections with Deen also distanced themselves, and non-porn website The Frisky dropped Deen’s sex-advice column from its site. In a matter of days, James Deen went from being the golden boy of porn to probably unemployable in the industry.

Of course, there was a backlash. Any allegation of sexual assault invariably brings forth strident deniers, and this was catnip for whorephobes. But it wasn’t just people accusing the women of “lying” and “slander.” One person replied to Stoya’s original tweet with “Rape a whore? Isn’t that just shoplifting?”

Defending a man accused of rape by calling his accuser a “whore” is especially irksome when that man is himself a sex worker. But there’s another reaction that bothers me, not only from outsiders, but also from a disturbing number of women in the sex industry. They’re defending Deen because Stoya accused him on Twitter.

Over the last two weeks, I have had a lot of conversations with people who say things like Deen is being tried in the court of social media. His professional reputation is ruined because he can’t prove himself innocent. None of them made a police report at the time, so how do we know it was REALLY rape? You can’t accuse someone of a crime without proof! There was a nearly constant thread of “innocent until proven guilty.”

But no one has filed criminal charges against Deen. He has exactly the same access to social media as his accusers do, he can talk to the reporters of his choice, and he has an agent and a lawyer to advise him. In my opinion, James Deen is not being victimized by the women who are saying he has harmed them.

When you say, “If it was rape, why didn’t you go the police?” here’s what it really means: If you don’t go to the police, you’re not allowed to talk about your sexual assault. Rape is like a ticket in a parking garage, apparently—if you didn’t get it validated by the powers that be, you will pay for that later. This is a silencing tactic, nothing more. No one spewing about “due process” to a sex worker who’s been assaulted until her ass needs stitches actually gives a shit about the sanctity of law.

And the law certainly does not give a shit about sex workers.

I have a lot of power and privilege for a sex worker, and still I can’t imagine going to the police if I were raped. To a sex worker, police are as likely to be the problem as they are to protect you from one. Take Oklahoma City police officer Daniel Holtzclaw, for example, who’s on trial for sexually assaulting 13 black women, many of whom had been sex workers. We’re supposed to get a rape-note stamp of approval from that guy?

Another gut-churning lesson on how sex workers fare in courtrooms is the case of Christy Mack, a nude model, dancer, and porn performer who was the victim of a horrifically violent attempted rape by her ex-partner, MMA fighter War Machine. Last year, War Machine, aka Jonathan Koppenhaver, allegedly entered her Las Vegas house, assaulted a friend of Mack’s who was also present, and then beat Mack so savagely that she suffered 18 broken bones, missing teeth, and a ruptured liver.

Koppenhaver was arrested and is now facing trial on 34 felony charges, including attempted murder. His defense? Since Mack was a sex worker, she enjoyed the attack. Koppenhaver’s defense lawyer, Brandon Sua, said in court that Mack’s career shows she had a “desire, the preference, the acceptability toward a particular form of sex activities that were outside of the norm.” Koppenhaver laughed openly when Mack testified in court, and at another point blew a kiss at the prosecuting attorney.

Even if Koppenhaver is convicted, it’s a stark reminder of what every sex worker learns: For us, there is no due process, no unbiased hearing. When it first became known that police were seeking War Machine for the assault, MMA fans on social media vilified Christy Mack as (of course) a lying whore. Then she tweeted pictures of herself in the hospital with shocking injuries, and public sympathy shifted considerably (if not completely) in her favor.

In the case of Deen, Stoya’s high social-media visibility is part of what made it safe for her to speak. Other women joined her, and their supporters made the hashtags #standwithstoya and #solidaritywithstoya go viral. If our suffering is plain, or our numbers many, then the court of public opinion is a place where sex workers may have a chance of prevailing.

James Deen is a porn brand whose stock has dropped. Doubtless that stings, but Deen is not headed to court and he’s not headed to jail, so the frenzied cries of “twitter lynch mobs” are absurd. It’s too soon even to say for sure his porn career is finished; other pop-culture heroes have recovered from sexual-assault accusations. Although really, if Deen truly can’t tell when he’s crossed over someone’s boundaries, is he really a guy who should be employed pushing them?

Moral questions about Deen’s behavior aside, it’s simply his job to have the consent of his scene partners, the professional trust of his producers, and the admiration of his fans. If he loses that? Then he loses his livelihood. That’s how fame works: You must cater to “the court of public opinion,” or the public will have no use for you.

Stoya punched a hole in the wall of silence about sexual assault against sex workers, as did all the women who joined her, and I’m grateful. You may decry the court of public opinion, but until sex workers are given equality before the law, we will use it, because it’s the only one open to us. recommended

What Happens To Men Who Stay Abstinent Until Marriage?

by Sarah Diefendorf

Russell Wilson and his girlfriend Ciara

Seattle Seahawks quarterback Russell Wilson and his girlfriend Ciara arrive at a White House State Dinner in April.

Seattle Seahawks quarterback Russell Wilson and his girlfriend, the singer Ciara, recently announced plans to remain sexually abstinent until marriage.

It was a vow that came as a surprise to many. After all, sexual purity is a commitment that is historically expected of, associated with – even demanded of – women. However, sexual abstinence is not something assumed of men, especially men like Russell Wilson.

Wilson, an accomplished, attractive athlete, embodies contemporary ideals of masculinity, which include style, wealth and, yes, sexual prowess.

So how does a man like Russell Wilson navigate a commitment to abstinence while upholding ideals of masculinity? Wilson’s status as an athlete and heartthrob is likely giving him what sociologist CJ Pascoe calls “jock insurance.” In other words, due to his celebrity status, he can make traditionally nonmasculine choices without having his masculinity questioned.

But what does it mean for a man who isn’t in the limelight, who makes a similar type of commitment to abstinence? And what does it mean for the women they date, and might eventually marry?

I’ve been researching men who pledge sexual abstinence since 2008, work that comes out of a larger scholarly interest in masculinities, religion and sex education.

While men make this commitment with the good intentions for a fulfilling marriage and sex life, my research indicates that the beliefs about sexuality and gender that come hand in hand with these pledges of abstinence do not necessarily make for an easy transition to a married sexual life.

Who’s Pledging “Purity?”

Comedian Joy Behar recently joked that abstinence is what you do after you’ve been married for a long time. Here, Behar makes two assumptions. One is that sexual activity declines both with age and the time spent in a relationship. This is true.

The second is that abstinence is not something you do before marriage. For the most part, this is true as well: by age 21, 85% of men and 81% of women in the United States have engaged in sexual intercourse.

purity ringIf we compare these numbers to the average age of first marriage in the United States – 27 for women, and 29 for men – we get the picture: most people are having sex before marriage.

Still, some in the United States are making “virginity pledges,” and commit to abstinence until marriage. Most of the data that exist on this practice show that those who make the pledges will do so in high school, often by either signing a pledge card or donning a purity ring.

Research on this population tells us a few things: that those who pledge are more likely to be young women, and that – regardless of gender – an abstinence pledge delays the onset of sexual activity by only 18 months. Furthermore, taking a virginity pledge will often encourage other types of sexual behavior.

Virgins In Guyland

But little is known about men who pledge and navigate this commitment to abstinence.

I was curious about how men maintain pledges in light of these statistics, and also balance them with expectations about masculinity. So in 2008, I began researching a support group of 15 men at an Evangelical church in the Southwest. All members were white, in their early to mid-20’s, single or casually dating – and supporting each other in their decisions to remain abstinent until marriage.

The group, called The River, met once a week, where, sitting on couches, eating pizza or talking about video games, they’d eventually gravitate toward the topic that brought them all together in the first place: sex.

On the surface, it would seem impossible for these men to participate in what sociologist Michael Kimmel calls “Guyland” – a developmental and social stage driven by a “guy code” that demands, among other things, sexual conquest and detached intimacy.

Rather, the men of The River approach sex as something sacred, a gift from God meant to be enjoyed in the confines of the marriage bed. At the same time, these men struggle with what they describe as the “beastly elements” – or temptations – of sexuality. And it is precisely because of these so-called beastly elements that these men find each other in the same space every week.

The men of The River grappled with pornography use, masturbation, lust and same-sex desire, all of which can potentially derail these men from their pledge.

It raises an interesting dilemma: to these men, sex is both sacred and beastly. Yet the way they navigate this seeming contradiction actually allows them to exert their masculinity in line with the demands of Guyland.

Group members had an elaborate network of accountability partners to help them resist temptations. For example, one had an accountability partner who viewed his weekly online browsing history to make sure he wasn’t looking at pornography. Another accountability partner texted him each night to make sure that he and his girlfriend were “behaving.”

While these behaviors may seem unusual, they work in ways that allow men to actually assert their masculinity. Through what sociologist Amy Wilkins calls “collective performances of temptation,” these men are able to discuss just how difficult it is to refrain from the beastly urges; in this way, they reinforce the norm that they are highly sexual men, even in the absence of sexual activity.

The River, as a support group, works largely in the same way. These men are able to confirm their sexual desires in a homosocial space – similar to Kimmel’s research in Guyland – from which Kimmel notes that the “actual experience of sex pales in comparison to the experience of talking about sex.”

A ‘Sacred Gift’ – With Mixed Returns

The men of The River believed that the time and work required to maintain these pledges would pay off in the form of a happy and healthy marriage.

Ciara, in discussing her commitment to abstinence with Russell Wilson, similarly added that she believes such a promise is important for creating a foundation of love and friendship. She stated that, “if we have that [base] that strong, we can conquer anything with our love.”

So what happened once after the men of The River got married? In 2011, I followed up with them.

All but one had gotten married. But while the transition to married life brought promises of enjoying their “sacred gift from God,” this gift was fraught.

Respondents reported that they still struggled with the beastly elements of sexuality. They also had the added concern of extramarital affairs. Furthermore – and perhaps most importantly – men no longer had the support to work through these temptations.

There were two reasons behind this development.

First, respondents had been told, since they were young, that women were nonsexual. At the same time, these men had also been taught that their wives would be available for their pleasure.

It’s a double standard that’s in line with longstanding cultural ideals of the relationship between femininity and purity. But it’s a contradiction that leaves men unwilling to open up to the very women they’re having sex with.

These married men and women were not talking to each other about sex. Rather than freely discussing sex or temptation with their wives (as they had done with their accountability partners), the men simply tried to suppress temptation by imagining the devastation any sexual deviations might cause their wives.

after marriage

After marriage, the men felt left to their own devices.

Second, these men could no longer reach out to their support networks due to their own ideals of masculinity. They had been promised a sacred gift: a sexually active, happy marriage. Yet many weren’t fully satisfied, as evidenced by the continued tension between the sacred and beastly. However, to open up about these continued struggles would be to admit failure as masculine, Christian man.

In the end, the research indicates that a pledge of sexual abstinence works to uphold an ideal of masculinity that disadvantages both men and women.

After 25 years of being told that sex is something dangerous that needs to be controlled, the transition to married (and sexual) life is difficult, at best, while leaving men without the support they need. Women, meanwhile, are often left out of the conversation entirely.

So when we urge abstinence in place of healthy conversations about sex and sexuality, we may be undermining the relationships that are the driving goal of these commitments in the first place.

No, Scientists Have Not Found the ‘Gay Gene’

By Ed Yong

The media is hyping a study that doesn’t do what it says it does.

A woman works with human genetic material at a laboratory in Munich May 23, 2011. On May 25, 2011 the ethic commission of the German lower house of parliament (Bundestag) will discuss about alternative proposals for a new law on the use of preimplantation genetic diagnosis (PGD). Preimplantation genetic diagnosis (Praeimplantationsdiagnostik) is a technique used to identify genetic defects in embryos created through in vitro fertilization (IVF) before pregnancy, which is banned by German legislation.

This week, a team from the University of California, Los Angeles claimed to have found several epigenetic marks—chemical modifications of DNA that don’t change the underlying sequence—that are associated with homosexuality in men. Postdoc Tuck Ngun presented the results yesterday at the American Society of Human Genetics 2015 conference. Nature News were among the first to break the story based on a press release issued by the conference organisersOthers quickly followed suit. “Have They Found The Gay Gene?” said the front page of Metro, a London paper, on Friday morning.

Meanwhile, the mood at the conference has been decidedly less complimentary, with several geneticists criticizing the methods presented in the talk, the validity of the results, and the coverage in the press.

Ngun’s study was based on 37 pairs of identical male twins who were discordant—that is, one twin in each pair was gay, while the other was straight—and 10 pairs who were both gay. He analysed 140,000 regions in the genomes of the twins and looked for methylation marks—chemical Post-It notes that dictate when and where genes are activated. He whittled these down to around 6,000 regions of interest, and then built a computer model that would use data from these regions to classify people based on their sexual orientation.

The best model used just five of the methylation marks, and correctly classified the twins 67 percent of the time. “To our knowledge, this is the first example of a biomarker-based predictive model for sexual orientation,” Ngun wrote in his abstract.

The problems begin with the size of the study, which is tiny. The field of epigenetics is littered with the corpses of statistically underpowered studies like these, which simply lack the numbers to produce reliable, reproducible results.

Unfortunately, the problems don’t end there. The team split their group into two: a “training set” whose data they used to build their algorithm, and a “testing set”, whose data they used to verify it. That’s standard and good practice—exactly what they should have done. But splitting the sample means that the study goes from underpowered to really underpowered.

001

There’s also another, larger issue. As far as could be judged from the unpublished results presented in the talk, the team used their training set to build several models for classifying their twins, and eventually chose the one with the greatest accuracy when applied to the testing set. That’s a problem because in research like this, there has to be a strict firewall between the training and testing sets; the team broke that firewall by essentially using the testing set to optimise their algorithms.

If you use this strategy, chances are you will find a positive result through random chance alone. Chances are some combination of methylation marks out of the original 6,000 will be significantly linked to sexual orientation, whether they genuinely affect sexual orientation or not. This is a well-known statistical problem that can be at least partly countered by running what’s called a correction for multiple testing. The team didn’t do that. (In an email to The Atlantic, Ngun denies that such a correction was necessary.)And, “like everyone else in the history of epigenetics studies they could not resist trying to interpret the findings mechanistically,” wrote John Greally from the Albert Einstein College of Medicine in a blog post. By which he means: they gave the results an imprimatur of plausibility by noting the roles of the genes affected by the five epi-marks. One is involved in controlling immune genes that have been linked to sexual attraction. Another is involved in moving molecules along neurons. Could epi-marks on these genes influence someone’s sexual attraction? Maybe. It’s also plausible that someone’s sexual orientation influences epi-marks on these genes. Correlation, after all, does not imply causation.

So, ultimately, what we have is an underpowered fishing expedition that used inappropriate statistics and that snagged results which may be false positives. Epigenetics marks may well be involved in sexual orientation. But this study, despite its claims, does not prove that and, as designed, could not have.

In a response to Greally’s post, Ngun admitted that the study was underpowered. “The reality is that we had basically no funding,” he said. “The sample size was not what we wanted. But do I hold out for some impossible ideal or do I work with what I have? I chose the latter.” He also told Nature News that he plans to “replicate the study in a different group of twins and also determine whether the same marks are more common in gay men than in straight men in a large and diverse population.”Great. Replication and verification are the cornerstones of science. But to replicate and verify, you need a sturdy preliminary finding upon which to build and expand—and that’s not the case here. It may seem like the noble choice to work with what you’ve got. But when what you’ve got are the makings of a fatally weak study, of the kind well known to cause problems in a field, it really is an option—perhaps the best option—to not do it at all. (The same could be said for journalists outside the conference choosing to cover the study based on a press release.)As Greally wrote in his post: “It’s not personal about [Ngun] or his colleagues, but we can no longer allow poor epigenetics studies to be given credibility if this field is to survive. By ‘poor,’ I mean uninterpretable.”

“This is only representative of the broader literature,” he told me. “The problems in the field are systematic. We need to change how epigenomics research is performed throughout the community.”

Putting A Ring On It

Hi There
I am new to this scene, and I have very little experience in anal sex and I am seeking your help and advice. I am a top but I have a problem keeping my dick hard or staying hard during anal sex. I find it harder to fuck an ass compared to fucking a pussy. Here is the problem: Once I get my dick hard, put on a condom and start fucking, my dick sometimes goes soft on me. Is that normal? How can I keep my dick hard long enough in the ass to enjoy the fuck? Sometimes even when my dick is hard, I find it hard to penetrate an ass. I use lube, so what am I doing wrong? People in gay porn can fuck and fuck like there is no tomorrow. I want to enjoy anal sex too!! Any advice? Please let me know if there is anything I can do to improve in this area?

Boy, you’re in luck, William! One of my most popular tutorials, Finessing That Ass Fuck — A Tutorial For a Top, is waiting for you.  Check it out! It will answer a lot of the questions you have about butt fucking. You should also know that this is the companion piece to my tutorial for ass fuckin’ bottoms handsomely titled: Liberating The B.O.B. Within. Don’t know what a BOB is? No to worry, all will be explained.

gettin it from behindBut before you disappear to do your homework, I’d like to address one of the specific issues you raise, about keeping your dick hard while fucking. You are right to point out that fucking an ass (male or female) is different from fucking a pussy. But regardless of what hole you’re invading, a nice hard stiffy is essential.

Are you familiar with a cockring, William? If not, I suggest you acquaint yourself with these amazing low-tech wonders. Here’s what you should do. Mozie on over to the Dr Dick’s Sex Toy Reviews site and search for my tutorial, Cockring Crash Course. (The search function in the sidebar will assist you.) Prepare yourself to be sorely amazed at the variety and functionality of these little devils.

Cock rings can create larger, firmer erections. Since blood flow enters your dick through arteries deep inside your dick, and leaves it through the veins near the surface of your tool; wearing a cock ring can help to keep more blood inside your dick shaft. And as all you rocket scientists know, blood is what causes erections in the first place. Also some men claim that wearing a cock ring intensifies their orgasm.armour up04

And while you’re on the sex toy review site, use the CATEGORY pull-down menu in the sidebar and look for cockrings. You’ll find it under the last heading, Sexual Enrichment. This will bring up all the cockrings we reviewed, and there’s a load of ‘em, don’t cha know.

I recommend the flexible and/or adjustable cockrings. These are generally made of stretchable rubber or leather. For the more daring there are the metal variety. These may look pretty, but they can be a bitch to put on and to take off. Here’s how ya do it.

  1. Pull your ball sack through the ring first.
  2. Follow this by popping each of your balls through the ring one at a time.
  3. Now bend your cock down and pull it through the ring.

As you can see, putting on one of these little buggers before you have a raging hardon is gonna make it a whole lot easier. To take the cock ring off, simply reverse these steps, pushing your flaccid cock back through the ring first, followed by each of your balls and finally your ball sack.

It’s absolutely essential that you not wear an inflexible (metal) ring for longer than a couple hours. Make sure you don’t buy one that is too small either. If your dick is turning an angry red or worse, purple, or it is cold to the touch, you’re in trouble. Take that ring off immediately. If you don’t you will risk serious injury to your precious johnson. Remember people, play smart with all your toys!

Good luck
