Jezebel does a piece on the most popular porn search terms by state.

Turns out that overall the term "creampie" is the most popular.

Most commentators at first have no idea what the term means, until it's explained to them that it's when a man ejaculates into a vagina during a porn scene.

The vast majority then replied "eww! that's gross!"

Excuse me? Given that porn is about filming sex, what could possibly be less gross and more natural than you know, a penis doing what nature evolved it to do?

Unless you find sex itself gross, I don't see, at all, how sperm in a vagina could possibly be considered gross.

What do these women think happens during sex?
