Pff, women are just as perverted as men, generally, but it comes out differently. Men are more or less expected to be sleeping with every woman above size B they meet starting at a certain age. For a woman to do that, it is less acceptable, at least here. Just a cultural thing, I suppose.
Totally agreeing with MaverickSawyer here, too. Relax and enjoy. No one is required to obtain a mate, temporary or permanent, as quickly as possible, and girlfriends are terribly inefficient status symbols anyway. May as well wait for a relationship actually worth fighting for to start fighting for a relationship.
