There is a correlation between infidelity and the size of a male’s testicles, researchers have found.

A study by scientists at the University of Oslo found that primates with bigger testicles were more likely to be unfaithful.

Petter Bøckman, Assistant Professor, said: “We can determine the degree of fidelity in the female by looking at the size of the male’s testicles. The less faithful the female, the larger the male’s testicles.

“If the male will only fertilise one female and has no competitors, he only needs sufficient sperm to reach the egg. If the female mates on the side, it is smart to have as many cars as possible in the race.

“Then, the male must have testicles that are as large as possible.”

Prof Bøckman said bonobos have particularly large testicles and mate in large groups whereas gorillas have small testicles.

He said: “There is an abundant flow of semen. Those who leave the greatest amount of sperm have the largest chance of fathering offspring.

“In gorilla troops there is only one male. Even though the gorilla has a small harem, he has no need for large testicles – his balls are tiny.”

Large testicles can increase the risk of testicular cancer, the study found.

“Animals with short lifespans may have enormously large testicles. In one type of grasshopper the testicles occupy half their body mass,” said Prof Bøckman

“The testicles are even larger in sea urchins. They spawn directly into the ocean. To increase the chance of fertilising an egg, the sea urchin is a huge testicle with a little shell around it.”

The testicles of humans are one and a half times larger than those of gorillas.

Prof Bøckman said: “This testifies with abundant clarity to life in our flock. We can pledge our fidelity until we are blue in the face, but this is evidence that our females are cheating.

“We are not like chimpanzees, where the female has four or five sexual partners every time she is in heat, but there is always a certain likelihood that the neighbouring male has dropped by.”

The testicles are also large in animals that have sex with many females.

Prof Bøckman said: “Male lions have huge balls. All the females in the pride must have sex at the same time. When the female lions in the pride are in heat, he must mate with all the females every half-hour for three days.”

8 Steps for Choosing a Strap-On Harness for Men

By Mistress Kay

Strap-on fun isn’t just for women. Men can have fun, too. Use these 8 steps to choose the best strap-on harness for your needs.

Deuce02

Did you know that even if you have a penis that you can still wear a strap-on harness? Yes, manufacturers make strap-on harnesses for the male-bodied as well as the female-bodied. While males can definitely wear strap-on harnesses designed for women, some find that the pressure it places on the penis and testicles to be uncomfortable. Strap-on harnesses for male bodies are designed with a penis in mind, providing much better comfort.

Strap-ons for people who have a penis can be used for a variety of play times. Some people like to use them as an alternative to penetrative sex (or in kinky contexts, as a “punishment” where the wearer doesn’t get to be directly involved in stimulation). Other people like to strap them on to continue the penetrative action after the penis has gotten soft (due to orgasm or other reasons). Yet others like to explore the idea of double penetration.

While some aspects are different, a lot of the things you’ll want to look for in your strap-on harness are going to be the same, whether you have a penis or not. There are a few key differences, but for the most part, any helpful suggestions you can find (like the ones below!) about finding a good-fitting strap-on harness are going to apply no matter what you have behind your fly.

Interested in trying a strap-on? Here we’ll take a look at this unique sex toy and provide some tips for choosing one for yourself.

Materials

Material can be an important concern for your harness. Material choice will affect the cost of your harness, how easy it is to clean, how comfortable it is for you to wear, how long it will last, and more. While leather tends to be the “premium” material for sex toy harnesses, it also is usually the most expensive and requires careful maintenance after use. Neoprene materials have picked up in recent years because of their ability to be tossed in the washing machine after use. Other materials may include nylon, velvet, cotton, spandex, and more. Much like buying a pair of underwear online, think about what materials have the properties you enjoy and try to find a harness in similar materials.

Double-Penetration or Single

DeuceSome harnesses for males are specifically designed to work well for single penetration. For people who want to continue having sex with a partner after they lose their erection (whether due to orgasm or other reasons), a harness designed for single penetration will hold the entire penis in a comfortable manner while the person can use the dildo that they’ve strapped on to the harness. In some cases, these harnesses may be designed for the penis to slip through the D-ring into the interior of a hollow strap-on dildo to make you “part” of the action.

For harnesses designed for double-penetration, your harness will help you take advantage of the penis you already have – while adding the ability to wield another one. These types of harnesses will have a spot where your biological penis sticks through and an O-ring where a dildo can be attached for easy double penetration.

Built-In Dildos

Some harnesses will include a built-in dildo. This dildo may be able to be removed to be cleaned. In most instances, it will include a hollow interior so that the wearer’s own penis can slide inside the dildo for a more comfortable wearing experience. However, if the harness was built for a specific dildo, the O-ring or the design may not allow the use of any other toys. When purchasing a dildo and harness set designed for use with one another, ensure you can use other toys with the harness down the line in case you decide to change up your toys.

Adjustment Points

Depending on how often you take it on and off and whether you’ll be sharing it with other people, you may have a preference to where the adjustment points for your harness are located and what they use. Nylon strap systems may be easier for you to use than buckle systems. Most people, however, agree that the easiest system is a Velcro fastening system, but some people find those to be unattractive for their personal preferences. Adjustment points that are available on your hip are going to be easier to adjust than ones that are located underneath the butt. While it can be hard to judge how easy the harness will be to adjust before you purchase it, try checking out reviews to see what other reviewers have to say about the usability of your potential harness.

Sizes

Unlike many other types of clothing, strap-on harnesses usually only come in a single, maximum size. Due to the adjustment system, this single size can usually be modified to fit a wide range of hip sizes, but it still has a maximum size. If you’re a plus-sized person, you’re going to want to pay attention to the maximum size measurement of your harness. Many harnesses will maximize at a size around 44″. Some harnesses will go up to 60″, and a few harnesses (usually designed for plus-size bodies) will go up to 72″ and above. If you have wider hips, you’ll want to pay attention to these measurements to ensure your harness will fit once you receive it. (Get some great sex positions to use too in 6 Sex Positions for Big, Beautiful Bodies.)

Strap Styles Deuce03

How the harness fastens onto your body will vary. The two most-popular styles include a “single strap” and a “double strap.” While both styles will include a waistband strap that goes around the hips, in a single-strap variation, there is a single strap that goes between the legs (similar to a “thong” style underwear) that holds the harness onto the body.

In a double-strap harness, there are two straps that slip between the thighs and go underneath the cheeks of the butt (similar to a jock strap). Depending on what you plan to do, you may prefer one style over another; but it’s all personal preference. If you plan on doing any anal play while wearing the harness, however, a double-strap style leaves the butt open for experimentation. At the same time, a single-strap style would put pressure on the anal area to help keep a butt plug in while using the harness. Think about what you’d also like to do while wearing the harness and purchase a harness that supports that.

Washability

Different strap-on harnesses will require different methods of care. If you’re okay with gently hand-washing your harness, materials like leather might be a good option. If you’d prefer the effortless method, you might want a neoprene material that can be tossed into the washing machine after use. Decide what type of harness works best for you. Of course, you should pay attention to the manufacturer’s recommendation for cleaning when you purchase it.

Special Features

While most male strap-on harnesses are pretty straight-forward, some do come equipped with special features. Some can use an optional “butt plug attachment” that attaches to the harness itself to hold a butt plug in for the wearer. Others may come equipped with special pouches that hold vibrators to add vibrations to the dildo that the wearer is using. Some may be waterproof or specifically designed for aquatic adventures. If you have something specific in mind, see if you can find a harness that works with your adventurous ideas.

Experimenting with the enjoyable world of strap-on harnesses for males can be full of exciting and enjoyable pleasure. With the above suggestions, you will hopefully have better luck finding that perfect harness to take you on that adventure. Don’t give up if your first harness isn’t your first love! Sometimes, it may take a couple tries to find that perfect one for you. Enjoy the ride!

What Makes These Dominican Children Grow Penises at Puberty?

By Michele Debczak

guevedoces

In the Dominican Republic, the phenomenon of children who were raised female appearing to swap sexes at puberty is so common it even has a name. Guevedoces roughly translates to “penis [or “balls”] at 12,” and it’s the result of a rare enzyme deficiency that delays crucial steps of male sexual development until puberty.

When guevedoces are born, they appear to have external female genitalia even though their genes and internal reproductive organs are male. Parents assume their children are girls and raise them as such. But when these children begin producing large amounts of testosterone at puberty, their testes descend and they grow a penis—in addition to all the other changes that come along with male adolescence. 

Sexual development normally begins in the womb, and the same is true for guevedoces. Whether the fetus has one X chromosome or two, for the first several weeks of development its genes follow the same blueprint for both sexes. Then, sometime around the eight-week mark, the sex chromosomes get to work. For males, the undeveloped gonads become testicles and they start to release male hormones, including testosterone. In a structure called the tubercle, an enzyme called 5-alpha-reductase converts the testosterone to a stronger hormone called dihydrotestosterone (DHT), which is necessary to develop external genitalia. It’s this hormone that turns the tubercle into a penis; without it, it develops into a clitoris.

The rare enzyme deficiency found in guevedoces leaves them unable to develop external male genitalia in the womb. They still produce plenty of testosterone, which triggers the development of internal structures like the epididymis and vas deferens, but the lack of DHT makes the babies appear female at birth. It’s not until the second surge of testosterone these children receive at puberty that they grow testes and a penis.

The condition is thought to be genetic, tracing back to the female founder of a small village in the Dominican Republic’s mountainous hinterland. Outside of the nation, it’s incredibly rare.

For some guevedoces, being raised as female wasn’t an easy experience. “I never liked to dress as a girl, and when they bought me toys for girls, I never bothered playing with them,” Johnny, who had grown up as Felicita, told BBC Two, which features these kids in the second episode of the series Countdown to Life: The Extraordinary Making of You. “When I saw a group of boys, I would stop to play ball with them.” When Johnny, now 24, began to undergo physical changes, he was taunted at school and called nasty names by his classmates. He’s had a number of short-term girlfriends since going through puberty and dreams of one day getting married and starting a family. Another child named Carla began the process of transitioning to Carlos at age 9; he can be seen receiving a smile-inducing haircut in the photo above.

Most people with this condition live out their adult lives as men, but some choose to undergo surgery and remain female. The discovery of this disorder in the 1970s led to the development of a best-selling drug called finasteride, which is commonly prescribed to treat benign enlargement of the prostate and male pattern baldness. (You may know it by the brand name Propecia.) The drug mimics the enzyme deficiency by blocking the action of 5-alpha-reductase.

8 lessons for my sexually uneducated teen self

By Scott Roberts

modern_teen

By what I can only assume was an issue with the timetable I ended up having sex education at least three times during my years of education at middle and high school (yes I went to a ‘middle school’).

And for all their effort I remember being confused, uninformed and altogether none the wiser when the teaching staff tried to inform us about the goings on of the birds and the bees, (a saying I actually still don’t fully understand the significance of. Birds don’t have sex with bees as far as I’m aware).

Having a partner who’s part Dutch and who received (in my opinion) the best sex education in the world, thanks to the Netherlands government, I’m taking the time to look back on my sex-ignorance and highlight some of the key things I’d wished I’d known back then.

1 – Porn is not an accurate representation of real bodies or real sex.

I could quote a load of statistics but I think it’s well enough known that my generation are among the first to grow up in a world where pornography is in such easy reach. I can hardly blame my education for being a little slow on the uptake of something relatively new, but for future sex ed it seems essential to incorporate teaching on how we should perceive pornography as fantasy and not based on real sex lives. It also seems more important to bring parents into sex ed to try and bridge the generation gap that the internet has caused.

2. How to properly check yourself.

I remember plenty of talks on what to do to prevent STIs but I cannot remember ever being told what’s healthy and good and what I should look out for in my own body. I learned more about my own body by visiting my GP for an MOT than I did from a whole series of sex education lessons. Even Youtube provided better sex ed than my school ever did thanks to guys like Riyadh K uploading videos on how to check your testicles for cancer – we were never told that in school.

3. Pleasure is one of the most if not the most important part of sex.

Pleasure was completely missed out of our sex education curriculum. There was such a strong emphasis on the adverse effects of sex and the dangers; the risks of STIs and unwanted pregnancy, that its main purpose was more or less completely ignored. An understanding of the body and pleasure seems essential if you’re going to teach sex ed. There is something intrinsically British about being embarrassed when communicating about our own bodies and all the weird and wonderful things they do. That needs to be swept away.

4. Some men have sex with other men and some women have sex with other women.

As a gay man (well, gay boy at the time) I was excluded from most topics covered by our sex ed. Everything catered to a heterosexual norm and the sex lives of gay people, let alone the relationships of gay people, were left well alone. Thank the lord for Queer as Folk.

5. The specific things you can do as a gay man to help protect yourself.

I only learnt of the real dangers for me as a sexually active gay man through taking some initiative and going to a clinic. I had no clue about hepatitis jabs and emergency HIV treatments and windows of infection. I learned a lot through being able to ask questions of someone I could trust who knows what they’re on about. I also found that going to a clinic completely reversed my expectations which were based on the stereotype of sexual health clinics being sleazy and disgusting. I found it to be a place where I could freely ask all the questions I had which weren’t being met by the teaching at school, (big up Worthing sexual health, woo!).

6. Relationships are a big part of sex education too.

There was so much focus on the physical that the emotional side was almost forgotten. All of the emotional side of things more often than not were put down to hormones. Those pesky hormones were responsible for everything! Nobody attempted to delve deeper into the way we were feeling emotionally and why we were driven to think that the Smiths really did understand us like nobody else did.

7. Consent. A topic that as far as I can remember was not even covered.

The darker side of things including abuse and rape was not touched on, which seems absolutely ridiculous. Teaching consent is essential, especially in an age where pornography is distorting the idea of what is perceived as acceptable and unacceptable in a healthy sexual relationship.

8. Confidence is the most important part of your body image.

In our teenage years we spend so much time obsessed with wanting to look good and fighting Mother Nature who has destined us to be spotty, greasy-haired, squeaky-voiced slobs. Accepting body image and being confident with your own body is probably one of the lessons that comes with age but it certainly would have helped having some reassurances from school forcing our eyes away from the skinny catwalk models and the chiselled muscle men that we were thinking we should look like.

I feel like this may have just turned into a list of failings of our education system. But maybe it isn’t ALL bad and maybe things are changing. If you had a similar experience or if you had a totally different experience of sex ed let me know your thoughts!

8 Sex Positive Things You Can Say To Your Kids That Have Nothing To Do With Sex

By

leaves

“Sex positive” is, I am pleased to note, a term that has been gaining more attention in recent years. A social and philosophical response to repressed, limited, and often judgmental attitudes toward sex and sexuality, the sex positive movement emphasizes that “good sex” is defined as safe, informed, consensual, and whatever else it also is beyond those things is best left up to the people participating in the act. That’s it, and I think that’s awesome. As a parent, I am already doing my best to encourage sex positive attitudes in my children, who are 4-years-old and 19 months — despite the fact that they have absolutely no idea what sex is, and I don’t have plans to get into what it is with either of them any time soon. No, this is not a contradiction, and it’s not hard to do.

What it comes down to is this: Sex positivity rarely exists in a vacuum. It’s usually part of a larger life philosophy that believes all people are entitled to happiness and respect. I have found that there are broad areas of overlap between the body positive and fat acceptance movements, feminism, and the LGBT community. As such, there is so much a parent can say to their child that lays the groundwork for them to have happy, healthy, and fulfilling sex lives (when they’re ready) that don’t necessarily have a thing to do with sex.

“Your Body Belongs To You.”

your body

So not only does no one get touch you without your permission, but you decide what happens to it. If you teach little kids that this is true in the non-sexual streets, they’ll be more likely to automatically believe it once they grow up and get between the sheets.

“If They’re Not Having Fun, You Have To Stop; If You’re Not Having Fun, They Have To Stop.”

latest

Totally stolen from “Thomas” of Yes Means Yes, but when someone else writes something so well and so succinctly why reinvent the wheel? This concept of consent and mutual happiness doesn’t have to have a thing to do with sex to A) be great life advice, or B) set the scene to talk about and understand sexual consent later in life. To quote the original piece once again: “What I said will mean a lot of things in a lot of contexts; but it will always mean the same thing. Regard for one’s partner is a basic component of respect.”

“Penis. Vulva. Labia. Vagina. Breasts. Testicles.”

penis

Using grown up anatomical terms for all of a person’s various bits and bobs does a couple of sex positive things. It enables your child to talk about their body specifically, which can enable them to be specific and clear if there’s a problem. It also puts “bathing suit area” body parts on the same level as “arm” or “foot,” which we have collectively decided are not parts that require euphemisms. None of our body parts are anything to be secretive or ashamed about. Yes, of course, children should be taught that “vulvas are private” or “only you or a doctor is allowed to touch your testicles,” but that’s not going to be conveyed by giving those parts cutesy names and getting all jittery when someone talks about them.

“Love Is Love.”

indifferent

Kids will ultimately not find non-heterosexual relationships confusing at all (just ask same-sex parents). If a kid has never met a gay couple before, they might be a bit surprised by the idea the same way my kid was surprised the first time he saw purple M&Ms. But after, like, five seconds it’s like, “Oh. So this is the same basic concept as literally any other relationship/M&M I’ve ever encountered in my young life. Cool. Whatever.”

This was perhaps best conveyed by this little chap a few years ago…

Point is, letting your kids know that anyone can fall in love with anyone else doesn’t have to be a “very special after school special” conversation “when they’re old enough.” Anyone who thinks kids can ever be “too young” to be aware of non-heterosexual romantic relationships, by asserting that, is essentially just admitting, “I think there’s something wrong and bad and dangerous and upsetting about non-straight people.” Do you not feel that way? Then do yourself, your kids, and the world the favor of unburdening yourself of the idea that kids need to be grown up and holding onto something sturdy before they find out that some kids have two mommies. This is something anyone who understands what love and relationships are can understand. This sets the stage for your child to know acceptance is not for a select few, but for everyone.

“To Each Their Own.”

i'mma be me

This is basically one of the central tenets of sex positivity, but, again, doesn’t have to be limited to sexual attitudes. It’s never too early to tell your kids, “Look, different people are made happy by different things. Different people believe in different things. And sometimes those things may seem strange to you… and that’s fine. You don’t have to do what they do any more than they have to do as you say or believe.” I cannot count the number of times a day I have to tell my son, “You do not get to tell your sister how to play with her toys. It doesn’t matter if you think she’s playing with it wrong. There’s no right way to play with a truck.” Some day he might even get it!

“Everyone’s Body Deserves Respect.”

i respect you

The life blood of the sex positive movement is the idea of mutual respect. Of course, the idea that everyone deserves respect is a core tenet of, like, common human decency and hopefully everyone strives to instill this value in their children regardless of their desire for them to be raised with sex-positive attitudes. So I’ll take it a step beyond “everyone deserves respect” and talk about emphasizing the idea that every BODY deserves respect. Kid bodies, adult bodies, your body, other people’s bodies, disabled bodies, fat bodies, thin bodies, black bodies, women’s bodies, etc., and any intersection thereof. We can’t define a “good body” simply as one that is pleasing to a viewer. A good body is one that enables the person who lives inside of it to do things and be someone that makes them happy. Body positivity is going to be clutch in laying the groundwork for sex positivity.

“You Are Loved And Valued.”

you is kind

Sex positivity is nothing without self-esteem. Also kids thrive on the stuff, so it’s a good idea anyway.

“I Am Here Whenever You Need Someone To Listen.”

i'll be there
