Here's what science says is the most dangerous sex position.

We now know who to blame when dicks get broken.

A new study out of Brazil (where they do all the best sex position studies) has revealed that the most dangerous sex position is "woman on top" or "cowgirl."

The study of 44 men with fractured penises was conducted to find out why this "relatively uncommon clinical condition" occurs, and what you can do at home to stop it from happening to you.

If you feel like squirming, consider that half of the men heard an "audible crack" that led them to suspect fracture.

The Independent reports that the woman being on top is dangerous "because the woman controls the penis with her entire body weight landing on it and is unable to interrupt it when it suffers a 'wrong way penetration'." After "woman on top," doing it "doggy style" (it really says "doggy style" in the study!) is the second most dangerous sex position.

So ladies, next time you're feeling lazy, remind your man that if you're on top, there's a pretty good chance his penis will audibly snap in half.
