Like the guys are all telling, you about the girl being selfish. they might be right , I really hate having to admit that but , I was thinking you guys were just fooling around a little , but her getting pleasure and you not. thats not cool. So if you have been friends for 4 years you should be able to talk to her, and tell her that she is being selfish. If you want a real relationship with her and this isn't all bull crap you should be able to talk about anything , and if not whats the point, drop her for the selfish child that she is .
