Ok guys, here’s one you can spring on your “you ain’t gonna stick that in there” chick.

Anal sex will make your butt bigger – go ahead, tell her! Cuz, you know, all that testosterone…medical facts, dudes!

Don’t know if this is a joke or not, but this question was asked on a forum called Steady Health.

One of the forum posters replied:

I’m speachless… Right now there have to be hundreds of men who have read this saying, “I wonder if my girlfriend would believe this.”

Good luck!

Exactly what we were thinking!

So now you can back up your endless badgering of her for a little back door action with some medical facts!
