3D-printed sex organs help blind students learn about sexual health

3D-printing technology is letting blind students experience comprehensive, accessible sex ed for the first time ever.

3D-printed sex organs help blind students learn about sexual health

By Katie Dupere

Advocates and researchers collaborated to create more than 18 3D figures that model sex organs during a various states of arousal. They range from a flaccid penis to a dilated vaginal opening, allowing students to “feel” their way though sexual health lessons.

While it may be a NSFW (let alone not-safe-for-school) endeavor, these models are game-changers for blind students who often need to learn about sexual health through verbal instruction alone.

Sex ed classes overall often rely on dull videos and static illustrations, and while that type of stale education is a disservice to all students, it presents a unique problem for blind students.

“That approach does a blind student no good whatsoever because they, of course, cannot see the pictures and videos.” Dr. Gaylen Kapperman, a professor at Northern Illinois University who was involved with the project, told Mashable via email.

Studies show that 61% of blind adults or those with low vision say their vision status had a negative impact on the way they were able to participate in sex education.

It’s a gap advocates and researchers at Benetech, a nonprofit organization specializing in tech for good, set out to solve by creating these models of various penises and vulvas.

“3D models are the only types of models that make any sense to blind people,” Kapperman said. “Many people believe that if you provide raised-lined 2D tactile pictures of sex organs that blind people will be able to generalize this information. [That approach] makes no sense whatsoever for blind persons.”

But these models don’t only break sex ed barriers for blind children. Researchers say the models could make the instruction more meaningful for sighted kids, too.

The project’s goal is to eventually provide open-source 3D printing files for teachers. This means school districts would only have to finance the materials and printers to make the models.

Many experts predict the technology will become a staple for schools anyway. Once a school district owns a printer, 3D printing is a low-cost way to create models for classroom instruction, making it ideal for schools on a budget.

A sizable 90% of blind students attend school with sighted children, relying on modified lessons to fully absorb material. But there are only about 61,700 blind students in the U.S. Buying commercial models of genitalia already on the market can cost up to $500 per model — something low-funded schools would likely be reluctant to do, especially when only a handful of blind students may ever pass through their district.

To develop prototypes, Benetech partnered with LightHouse for the Blind and Northern Illinois University, where the models were first tested on blind college students. The project was funded entirely by a private Benetech donor.

Now in the second phase of the pilot program this spring, the models will make their ways into the hands of middle school and high school students — the target demographic.

By the end of the 2017 school year, researchers hope to have feedback from students on the current prototypes. Then they’ll release files with detailed printing instructions for classroom use.

Benetech plans to offer pre-printed models to accommodate schools without 3D printers, for a fee much lower than commercial models.

“It is our hope that these models will be an effective teaching tool for teachers to communicate sex education in a way that works for students who are blind and visually impaired,” said Dr. Lisa Wadors Verne, program manager of education and partnerships at Benetech.

Why Generation Tinder won’t go back to dating ‘the old-fashioned way’

Share

By Jenny Noyes

“My most memorable Tinder date?” Kate Iselin gestures as if to say get ready. “It was a gentleman who invited me to lunch, took me to the food court at Martin Place and showed me a photo of his penis. Soft.”

It’s not the fondest memory Iselin – a writer and former sex worker – has of her experiences on the app. But the negative and the bizarre do have a tendency to stick with you.

Horror stories aside, Iselin, 28, is overwhelmingly positive about the impact apps like Tinder have had on the contemporary dating experience. And she’s not alone.

Despite a steady stream of articles about Tinder “killing romance”, making people depressed, or putting them in danger, the app and others like it are as popular as ever (even if some users are loathe to admit it).

Iselin herself has recently returned to 30 Dates of Tinder, a blogging project she’d abandoned a year ago due to “personal stuff” including a relationship. The concept is fairly self-explanatory: she goes on 30 random dates, and writes about them. Now halfway through, she’s accepted every date request received – “provided the date location was safe and they didn’t seem like a closet serial killer,” she says.

Clearly, there’s an appetite for reading stories about Tinder – and part of that is a fascination with what can happen when virtual strangers attempt to light a flame.

But as dating via Tinder increasingly becomes the norm, it’s less about the novelty of using a phone app to date people off the internet. Four years since Tinder launched, Iselin says she’s returning to her project with “a slightly more serious goal”. It’s now more about answering an age-old question than exploring a curious new technology: “To prove that love exists.”

Of course, the proof is already out there among the growing number of successful, lasting relationships launched via Tinder or its myriad competitors. These apps aren’t just facilitating one-night stands. People are finding lasting love in such significant numbers it is no longer considered “weird” to have a partner found online.

Fairfax Media columnist Giselle Au-Nhien Nguyen has met almost all of the people she’s dated, in her 28 years, online. Whereas five to 10 years ago there was a stigma attached to meeting people via the internet, it is now “completely normalised” among Gen-Y.

“Most people I know in relationships that have started in the last few years have met their significant others on Tinder,” she says.

Eliza Berlage, 26, met her boyfriend of 10 months on Tinder. She says it’s really a numbers game. “You could go to so many bars, libraries, music festivals, house parties, and still have as much luck … just swiping it lucky and giving it a chance and seeing how it goes.”

With numbers comes choice. And according to Iselin, it’s the choice these apps offer that makes them truly revolutionary – especially for women, minorities, and people whose preferences lie outside the norm.

Although there are some who feel nostalgic for the pre-Tinder dating scene, Iselin reckons women have never had it better; and she doesn’t see us ever going back.

“I know a lot of people say, ‘I would never use Tinder because I want to meet the love of my life the old-fashioned way’. But when we talk about old-fashioned times, we’re talking about a time when women in particular did not have a lot of choice in meeting partners.”

The same goes for people who may be otherwise constrained from exploring their sexuality ‘the old-fashioned way’, says Senthorun Raj, Grindr enthusiast and academic in law and gender studies.

“For people who are busy, those who have social, mental, or physical mobility issues, or individuals who are worried about ‘outing’ their sexual or gender identity in public spaces, dating apps can be a more comfortable way to chat, socialise, and become intimate than meeting people at clubs or bars,” he says. “For same-sex-attracted and gender-non-conforming people especially, these apps can be lifelines to connect with others dealing with similar experiences.”

What’s more, they have the ability to make connections “with people who we would never encounter in the places or circles we normally frequent,” he adds.

Of course, it’s not all rainbows, love-hearts and wink emojis for women, racial minorities or LGBT people. Prejudice and harassment is a real issue – but Raj says it would be a mistake to suggest apps like Grindr and Tinder have unleashed it.

“While Grindr does not cause these stereotypes, apps do make it easier in some ways to express harmful racial, age, and other ‘preferences’ because of anonymity or because the lack of ‘in-person’ interaction makes you feel like what you say or do online is … subject to less critical scrutiny.”

Nguyen says rape threats and racist, sexist comments are things she’s personally had to deal with just as much offline as on dating apps and social media.

“There’s such a big moral panic when it comes to online dating and safety, and it’s valid but we also need to remember that women face this everywhere. It really comes down to better education in schools about consent and respectful connections, and also the apps ensuring that they take reports of violence seriously.”

Sex and relationships expert Cyndi Darnell agrees that while mobile dating apps have revolutionised the sexual choices available and the ease with which users can access them, ultimately better education is needed to improve the human interaction side of things.

“We’re still operating on a very, very, very limited consent framework in terms of discussions around sex and pleasure … and yet our technology is far more advanced than that,” she says.

“There’s no app for getting over awkwardness. There’s no app for managing sexual anxiety. That’s the thing we need to remember: just because there is more access to sex, it doesn’t mean the quality of the sex has improved. We mustn’t confuse quantity with quality.”

Then again, there’s quality to be found – especially if you’re willing to put in the effort. “I’ve been on excellent dates and I have friends who’ve ended up in the most magical relationships,” says Iselin, who’s confident she’ll achieve her goal in one way or another by the end of her 30 dates.

“We are the generation now going to Tinder weddings. There are Tinder babies. I think that’s really exciting, and that gives me faith.”

10 Things Scientists Discovered About Sex This Year

Share

By Justin Lehmiller

This year has been memorable for a lot of reasons, but one that may not be immediately obvious is that we learned a lot about the science of sex in 2016. Among other things, sex researchers brought us one step closer to a male version of the birth control pill, they debunked the idea that porn kills love, and they discovered that having a cat just might make you more inclined toward kinky sex (yep, you read that right). Let’s take a closer look at these findings and some of the other fascinating things scientists taught us about sex in 2016.

Americans are warming up to the idea of open relationships.

Americans are more interested than ever in consensual non-monogamy (CNM), or the practice of having multiple sexual and/or romantic relationships at the same time. A study published in The Journal of Sex Research in May found that Google searches for two forms of CNM—open relationships and polyamory—have significantly increased across the past decade. At the same time, a study published in the Journal of Sex & Marital Therapy found that more people are practicing CNM than previously thought: in a nationally representative survey of single Americans, more than 1 in 5 said they had been in a sexually open relationship before. Table for more than two, please.

We’re getting closer to a male version of the birth control pill.

An October study from The Journal of Clinical Endocrinology & Metabolism reported the results of a clinical trial in which men were given hormone injections designed to suppress their sperm production. The results were stunning: over the course of a year, the pregnancy rate for couples taking part in the study was just 1.57 out of 100. Unfortunately, however, the rate of side effects was very high, which led an external review board to recommend shutting down the study. Although this injection won’t be hitting the market, this study provides optimism that we’re not too far off from having a male equivalent of the female birth control pill.

Millennials are identifying as LGB at much higher rates than Gen Xers.

In January, the CDC released a report revealing major generational differences in Americans’ sexual identities. Specifically, millennials aged 18-24 were almost twice as likely to identify as gay, lesbian, or bisexual than Gen Xers aged 35-44. Millennials were more likely to report having engaged in same-sex behavior, too. However, whether this means same-sex attraction is actually increasing or if it’s just a sign that younger folks are more comfortable acknowledging their non-heterosexuality, we can’t say for sure.

The HPV vaccine has been wildly effective at reducing cancer.

In August, scientists reported that, in the ten years since the first vaccine for the human papilloma virus (HPV) was administered, rates of cervical cancer have been halved. If we can increase vaccination rates even further, there’s a chance that HPV-related cancers—including those of the cervix, anus, throat, and penis—could be eradicated within just a few decades.

Porn doesn’t change how men feel about their relationships.

A classic study from the 1980s found that heterosexual married men reported less love for their wives after viewing images of sexy magazine centerfolds compared to images of abstract art. This year, researchers tried three times to replicate the effect, but found nothing. Nada. Zip. Zero. These findings suggest that porn probably doesn’t kill love after all.

BDSM acts can produce an altered state of consciousness.

In May, a study published in the journal PLOS ONE looked at the psychological experiences of people who took part in an extreme masochistic ritual in which their skin was pierced with hooks that had weights attached. These participants demonstrated evidence of an altered mental state known as transient hypofrontality, described as “reductions in pain, living in the here and now, little active decision making, little active logic, and feelings of floating and peacefulness.” This suggests that BDSM acts have the potential to be a very spiritual experience.

We might be able to treat low sexual desire by electrically stimulating the brain.

In a November study published in the journal PLOS ONE, researchers found that delivering electrical stimulation to the brain changes the way we respond to sexual stimulation. Specifically, a targeted cranial “zap” appears to enhance the response that occurs in the brain’s pleasure centers. This suggests that we might actually be able to use brain stimulation as a treatment for people who complain of low sexual desire in the not too distant future.

Sexual arousal puts us in a risk-taking state of mind.

A January study published in the Archives of Sexual Behavior reveals that being horny can make us susceptible to taking risks, including those that are both sexual and non-sexual. In one study, participants who watched an X-rated film subsequently expressed more willingness to keep having sex after noticing a broken condom. In another study, sexually aroused participants made riskier moves in a game of computerized blackjack. These findings suggest that, when we’re feeling hot and bothered, well, we can’t be bothered to properly evaluate risks.

Women can detect when other women are ovulating, an ability they might use to protect their relationships.

In an April study published in the Journal of Personality and Social Psychology, researchers showed female participants photos of a woman who was either ovulating or not. Those who saw an ovulating woman were the most worried about keeping their partners away from her, but this was only true for participants with attractive partners. This suggests that women may have evolved the ability to pick up on other women’s ovulation status as a means of helping them to guard desirable mates from potential relationship threats.

Having a cat might increase your interest in kinky sex.

A July study published in the journal Evolutionary Psychology reported that people’s attraction to kinky sex depended upon whether they had been infected with toxoplasmosis, a parasitic disease that can be passed from cats to humans. Specifically, those who said they had been infected were more into bondage, violence, zoophilia, and fetishism. Why is that? The researchers suspect that it’s because this infection affects the circuits of the brain involved in fear, given that in mice and rats, toxoplasmosis switches their natural fear of cat smell into an attraction toward it.

Here’s to hoping 2017 is another mind-blowing year for sex research!

7 Butt Play Tips for Bum Fun Beginners

Share

By 

As a man who likes men, I can confidently say butt play isn’t easy. Bottoming can be back-breaking work, and topping is hard AF. But, besides that, it’s also unpredictable. You never know what’s going to happen. Is it going to hurt? What if he poohs on my peen, or worse, what if I pooh on his peen? Are farts a turn-off?

If you’re on your first anal adventure, you probably have tons of questions about the ins and outs of bum fun. Don’t worry. It’s normal. No one’s born an expert in anal and everyone starts out as a butt play beginner. So, if you’re new to fifth base and ready to explore the magical world of buttholes, this one’s for you.

Before we get started, let’s start by stating the obvious: The first time you have a dick up your ass, it feels like you have a dick up your ass. But, with proper preparation, you can enjoy every satisfying second from the moment of penetration to the flash of a climactic finish. Here are seven tips for butt-play beginners.

1. Tidy up

Ok, everyone has an opinion about cleaning out. Some guys are all for it while others believe the process is bad for your bowels. We’re not saying you need to hook up to a garden hose every time you take it, but a wet wipe never hurt anyone. Whether you plan to top or bottom, it’s nice to have a clean workspace. What if your man wants to finger your ass while you pound his purple starfish? It could happen, and you’ll want to be fresh(ish).

2. Start small

Start with something smaller than a cock, like the tip of your index finger or pocket bullet. By massaging the anus, you can loosen up the sphincter muscle and introduce the notion of penetration.

3. Go slow

Whether you’re inserting a pinky finger or a penis, go slow and find your groove. If you’re topping, going slow allows your man’s body to acclimate to the sensation of being penetrated. And, if you’re bottoming, you’ll appreciate the extra time to adjust to his length and girth.

Yes, when porn stars shove it in and go straight to pound town, it’s hot AF. but, in reality, it can be uncomfortable and ruin the whole experience. So, or the sake of the hole, slow your roll.

4. Reach around

If you’re the one playing the hole, distract your man with a reach around. This technique works particularly well if he’s on his hands and knees (aka in table position). Here’s what you should do: As you work his hole with your fingers, reach around and tease his shaft, balls and taint with your other hand.

It will drive him wild and take his mind off your fingers that secretly slipped inside.

5. Rim don’t ram

This one is self-explanatory. For tops and bottoms alike, it’s strangely tempting to ram it (your penis, a finger, etc.) in and get right to the rough stuff. Unless you’re into receiving or inflicting pain, don’t do it. Even if the bottom is ready to be penetrated, a forceful entry can make taking it too painful. So, regardless of your weapon of choice, rim the edge and carefully insert whatever your welding into the hole. Also, before you start poking around back there, lube up. Lube is your best friend

6. Communicate

Communication is key to just about everything. When it comes to sex, it’s vital. Whether you’re catching or pitching, ask your partner what feels good and before you perform any crazy maneuvers, talk to your man. Butt play is a lot more fun if you’re communicative.

7. Take fiber

If you’re not into douching but want to be somewhat clean, add extra fiber to your diet. The easiest way to increase your fiber intake is to add a supplement like Pure for Men to your regime. The ingredients in Pure for Men act like a broom and sweep out your insides. A clean butt breeds confidence, which makes it a lot easier to let someone put their finger up your ass.

8. Relax

The most important thing to know about butt play is that relaxing is fundamental. You have to relax. If you’re tense or uncomfortable about ass play, you or your partner could get hurt. So, unwind, grab some lube and explore your backdoor.

Is His Semen Normal?

Share

All spunk is funky, but sometimes it is *too* funky.

By

jizz

Very many things about the male human body are a mystery. Penises, hy? Those tiny nipples, what!? But dip beneath the hairy surface of a man’s skin, and even more mysteries await, hiding away in his male depths.

While usually contained, safe and sound inside of the body, semen is a fluid most people eventually come into contact with, but also do not know very much about. If it weren’t for Samantha Jones calling attention to the phenomenon of funky spunk in the “Easy Come, Easy Go” episode of Sex and the City in 2000, women the world over may have lived in quiet misery, forever perplexed by the unpleasantness of the male sex fluid.

To help educate the masses on the contents, and, yes, healthy range of funkiness in semen, Cosmopolitan.com spoke with a urology specialist and sexual health counselor about all things semen.

How semen should look

Aleece Fosnight, a urology physician’s assistant and sex counselor with AASECT, explained that healthy semen should be a milky white or slightly grayish color. “Right after ejaculation, it’s pretty thick,” Fosnight said. “And 25-30 minutes later, it becomes clear and runny.” The change in fluidity is to help aid in reproduction, and thin out the cervical mucous to aid in the implantation of a ~fertilized egg~.

How semen should (generally) smell and taste

Semen is a bodily fluid. Can you name any bodily fluids that smell like roses or taste like freshly baked cookies? No! There are none. So as a bodily fluid, you can expect semen to have a specific taste and odor that isn’t necessarily going to be lovely. Just to clear that right up.

The thing to note about semen is that it’s a vehicle for delivering sperm through a vagina. So everything in it is meant to aid in that process. Semen is mostly made up of sperm, proteins, fructose (to help energize the sperm for transport), and seminal fluid. Fosnight said the typical pH of semen is somewhere around 7-8, or slightly alkaline. The vagina, on the other hand, has a pH between 3-5, or slightly acidic, so the alkaline nature of semen helps keep the sperm alive in an acidic vaginal environment (are you having fun yet?).

Because of it’s slightly alkaline pH, Fosnight said healthy semen should have an “ammonia or bleach-like kind of a smell,” and will taste a bit sweet (because of the fructose) and salty — like the perfect trail mix, in drinkable liquid form, straight out of a penis!

Something Fosnight clarified was that semen left dormant for too long will start to develop a more concentrated taste or smell. Think of it like a stagnant body of water, collecting film and attracting flies. To keep semen from developing a stronger taste or odor — and also to promote prostate health — studies have found that ejaculating at least twice a week is beneficial to a man’s health.

That thing about food changing his taste is true

Remember when Samantha Jones makes the guy with the spunky funk choke down a series of wheatgrass shots in an attempt to improve his semen flavor profile? According to Fosnight, that wasn’t the smartest move.

Although there’s been very little research done on the subject, health care professionals often hear anecdotally from patients that certain foods can slightly affect the taste of semen. While Fosnight said it’s normal for fruits, which are high in sugar content, to change the taste of a person’s semen, vegetables generally don’t have much of an effect.

“Smoking can change the taste,” Fosnight added. “It will have more of a bitter taste to it with smoking and with alcohol.” So, no one’s saying you should avoid ingesting a mouthful of piping hot semen after your partner’s spent the night having too many drinks and then *whoops!* accidentally chain-smoking outside of the bar, but know that semen might taste especially bitter and, ahem, spunky after such an occasion.

When the spunkiness is trying to tell you something

Though there aren’t very many health issues that can be spotted based on a person’s semen, there are a few things to look out for. “A lot of times guys won’t notice it, so partners report if there’s something wrong,” Fosnight said. She also added that at her practice, they call this “when semen goes bad.”

The things to look out for are changes in color. “The biggest thing is if it has a yellow or green appearance to it,” Fosnight said. “Like a prominent yellow or opaque consistency.” An opaque yellow or green color is typically a sign of an STI — usually gonorrhea. A guy whose semen has changed colors like this should definitely see a doctor, and avoid sex until any sort of infection is either ruled out or treated.

It doesn’t happen all too often — Fosnight estimated maybe once in a lifetime for most men — but a busted blood vessel in the prostate (which is responsible for carrying semen out of the body) can cause the semen to have a red or brownish color. If that color normalizes within a few days, there’s nothing really to worry about. But as with any health concern, a persistent discoloration should result in a doctor’s appointment.

While not super common, blood in the semen is often indicative of a prostate injury, explained Fosnight. These can be caused by using anal toys or putting pressure on the prostate, and if the bleeding subsides and doesn’t come with any other symptoms like high blood pressure, things are fine.

As long as a man is doing his due diligence by having regular STI tests, regular prostate exams when he turns 40, and just FORCING himself to ejaculate a couple times a week, semen should be pretty healthy. It may never taste like frozen yogurt, but at least it will be healthy.
