Hi! I am a 15 year old female and I think I may be bisexual, I have talked to a couple friends (who are straight) that I trust, They either said "It's just a phase don't worry" Or "There is only one way to know and that is to have sex/kiss another female." But I don't know any lesbian girls to do that with! I'm pretty sure it's NOT a phase but I need to know how to find out if I'm bi or not....
