10 Things You Never Knew About Oral Sex, According To Science

Blowjobs. Eating someone out. Giving a beej. Going down on someone. Whatever you want to call it, we all know the basics about oral sex: it involves one person licking or sucking another person’s genitals… and while that explanation of it does not sound sexy or appealing at all, most people really, really love it. But what about more than the basics? Do we know why people give each other oral sex, besides the fact that they want to make each other feel good? Do guys really have a hard time going down a girl? Does oral sex actually increase your risk of cancer? There’s only one way to find out, and that is to turn to science – there are a bunch of studies that have been done on oral sex that reveal some pretty interesting information.

While this scientific research will certainly tell you some things you never knew about oral sex, it also shouldn’t be taken as the Rule. Keep in mind that some of these studies are very small and need more research. With that disclaimer in place, let’s discuss the strange things we can learn about third (or fourth, depending on your views on what sex means) base. It’s more complicated than it seems! What should you do with this info? I say keep it in the back of your mind for that moment a conversation needs a boost. Or, you know, just amuse yourself. Here are some facts about oral sex discovered by science that might blow your mind: 

Teens Say It Doesn't Count As Real Sex

When you think about it, the term "real sex" is pretty silly. Most people think of "real sex" as penetrative sex, and that isn't fair to anyone who isn't straight. "Real sex" should be what you think it means! But a recent study on sexual behavior done on almost 600 college students across 29 US states found that 60 percent of teens don't think of oral sex as "real" sex. Interestingly enough, it's not just heterosexual couples who feel this way. The article points out that, "Recent studies revealed that some gay males regard penile-anal penetration as resulting in loss of virginity, but not oral sex or non-penetrative sex, and lesbians may regard oral sex or fingering (the act of stimulating the vagina with fingers) as loss of virginity. But, due to the traditional view is that virginity is only lost through vaginal penetration by the penis, members of the LGBT community assert that the term virginity is meaningless to them." What are your thoughts?

Women Who Perform Oral Are Happier

A State University of New York study from 2012 found that performing oral sex on a male can make women happier - and no, this isn't something made up in a men's magazine. The study compared the sex lives of almost 250 females to their mental health, and discovered that women who give oral sex to men are happier. This is because of semen... seriously. Semen, apparently, has mood altering effects, and besides making you happy, it can help you sleep better and make you feel more affection towards others. So, the next time you want to get in a good mood... give a blowjob?

We Have Oral Sex To Get Accustomed To His DNA

Here's something weird: a recent study found that women give oral sex because swallowing a man's semen makes them accustomed to his DNA. This actually helps women get pregnant, because swallowing semen keeps our bodies from seeing it as foreign. I realize that sounds INSANE, but hey... it's science.

Men Give Oral Sex To See If A Woman Is Cheating

So then why do men give women oral sex? According to science, they go down on a woman to find out if she's cheating on him or not. The study found that men are more likely to perform oral sex on attractive women when they're in long-term relationships. The authors of the study argued that this is because they're more worried the woman is going to cheat. Apparently, they think (consciously or subconsciously, it's not clear) that they will be better able to detect another man's semen by going down on a woman. Um... okay.

It Might Increase Your Risk Of Cancer

Remember when Michael Douglas got cancer and he was all like, "LOL it's Catherine Zeta-Jones' fault because I eat her out too much?" Okay, that isn't exactly what he said, but it's basically what he said. At first, doctors said this was wrong, but recent research shows it might be true. A study that is the first of its kind, published in the US journal JAMA Oncology, "shows conclusively the human papillomavirus-16's (HPV-16) presence in the mouth leads to the development of mouth and throat cancer." So, giving oral sex in general doesn't increase your risk of cancer, but giving oral sex to someone with HPV does. This is just another reason to get tested before fooling around.

Oral Sex Might Make Women Healthier

In general, though, if you don't have HPV, oral sex can actually make you healthier. Research has found that orgasms from oral sex boost your mood, and also help your immune system. Plus, researchers said, “On top of that research, one other recent study examined I think 200 or so heterosexual and homosexual couples. Half focused their sex life heavily on oral and the other half didn’t and those that did found greater intimacy, reduced stress levels and other health benefits."

Women Are More Likely To Give Oral Sex

Surprise, surprise! A study from this past spring found that women are more likely to give oral sex than men, even when they don't want to. Researchers interviewed 71 people between the ages of 16 and 18-years-old and found some unsettling differences. They discovered that young men were more likely to say negative things about a female's genitals, and so both men and women found it "more distasteful and a 'bigger deal' for men to perform oral sex than women." And because of that kind of gossip, the study found that guys were more likely to say they didn't want to preform oral sex on someone, while young women were more likely to stay quiet and do it, even if they didn't want to.

Guys, that makes me really sad! No one should ever feel forced into performing oral sex!

Giving Oral Can Make Men Healthier

It looks like those young men who won't give oral sex are doing it wrong - research has shown that men who give oral sex to women are healthier. When a man performs oral on a woman, she produces hormones like oxytocin and DHEA, which are proven to have protective elements against cancer and other diseases - and men absorb that while down there. Those hormones also encourage sleep and can even help prevent migraines.

Men Enjoy Giving Oral More Than Women Do

While men might not give as much oral sex as women do, a study found that men are more likely to enjoy performing oral sex more than women do. So, basically, the dudes who ARE giving oral sex have a lot more fun than women who give oral sex. There are lot of reasons this could be true, but it is interesting.
