How many parts?

I always worry that girls are going to think I'm hitting on them if I try to make friends with them. Partially because I've never initiated a friendship with a girl before. They usually happen because I hang out with their brother or their boyfriend. And partially because I'm part lesbian. But I'm never on the prowl since I have a boyfriend. And I've never had a girlfriend so I wouldn't know how to pick up a chick anyway. Maybe when my boyfriend leaves me for Hong Kong I'll figure it out and go find some hot chick to make out with.
