why do guys think its hot when girls are bi or lez?

Answer 1

Well....it just IS.

Guys like sex, and they like to think about sex. And when a guy thinks about sex, naturally, there must be a guy in the mental picture. Now guys don't even like thinking about thinking about a naked guy and all(even if it's them). so even in his mind he won't 'look' at the guy there. The same is true for movies.

But Bi/Lez are perfect for this problem. No matter where a guy looks he sees a girl. He does not have to look away at all. It gets the 'guy' out of the sex picture.
