We all do it. Sex is a normal part of life. Some of us do it a lot more than others, and some of us only dabble into it once in a while. Bottom line, sex is one of the most reoccurring thoughts in the human mind and drives a lot of our everyday emotions.

Some of you reading this probably think that you’re an expert when it comes to sex, but I bet you there are probably a lot of things you didn’t know about sex.

I’m not talking about sex skills and technique, rather, scientific facts and studies regarding sex and let me tell you, some of them are pretty far out there! It makes me wonder why and how there was even studies conducted on some of these things in the first place.

Here is a list of the weirdest sex facts I’ve ever heard of:

1. Oral sex is not only a human thing:
Macaques, cheetahs, hyenas and goats also perform oral sex on their partners-and get this, in many cases they swallow!

2. Porn isn’t just a human thing:
When monkeys at Duke University were offered the opportunity to pass up their fruit juice in exchange for images of female monkey asses, they gave their drinks right up.

3. Looking at threesome porn helps a man produce better sperm:
Studies show that men tend to create better sperm when competition is high. And there is no greater competition quite like the sight of a chick getting pounded from two guys at once.

4. The bigger the balls, the more promiscuous the female of your species:
If the females in the species are bigger sluts, then the male’s balls will be a lot bigger. Female chimpanzees are very promiscuous, and the male chimpanzee has balls ten times the size of those of gorillas, who often enjoy monogamous relationships with their partners. Humans fall in between the two.

5.Bigger brains come at the expense of your balls:
Sorry for all you geeks and braniacs out there, but studies show that because large brains take a lot to develop and keep running, they come at the expense of other things in the body. Also known as, your balls.

Not sure what you got out of these facts, but there is one thing for sure that you can do right now. Go and look at some free porn with threesomes and you can improve your sperm production!
