Well, as a female, with platonic male friends, I know what I do. I will talk about other men with someone that I consider to be my "boy", buddy or whatever. I'll even ask him about his women. It's comfortable and casual and I don't feel the need to be "done up" around him. Also, with someone that I am interested in, I will call him. Initiate hooking up, etc. Someone who is my friend or my boy can come around when my girls are there and we're chillin' watching movies, being silly, having our little impromptu male/female debates. I just consider them to be good people who I am not attracted to. True, sometimes your "boy" might flip it on you and throw you off with the "what about us" conversation. Its uncomfortable, but if you care about that person as a friend and a person in general, you will do the right thing and not string them along. That's how I handle things.
