The myth is that men are sex-obsessed beasts who can think of and are concerned with nothing else.

The reality for most men: “This woman is naked with her legs spread and she’s pulling down my pants. Maybe she’s just tired? Or doesn’t like my pants? She probably doesn’t actually want sex. This is a trick or something. I better not chance it. Don’t want to be a creep.”

The above (only slightly exaggerated) happens so very often to men who are only used to disdain and rejection from women.
