Seriously? What was going through someone's mind to think "I wonder what would happen if I put THIS, in THERE". Did someone miss or something and realize it felt good? And was the girl like ? Or did some sick fuck some place down the line feel like doing it all of a sudden?

Asshole= hole

Doesn't take a genius.

What makes you think the first instance of anal sex involved a woman?

Penis envy. Then came along pegging.

Don't get sassy with me. The difference being that it's INSTINCT to stick your penis inside a girls vagina. Not her mouth or her anus.

the anus produces pheromones. scientists have discovered that homosexuals respond to pheromones from the anus of people that are of their same sex, especially other homosexuals of their same sex. and heterosexuals respond more to heterosexuals of their opposite sex.

and if youre a straight guy, you gotta admit you like looking at a girls butt more than a guys butt. it should be the same with a girls anus and anal sex may have had evolutionary advantages. it may still

The Egyptians?

Nah, the Greeks.

k sorry

But I mean, it's true

Prostitutes.
