I'm not sure whether I'm straight or bisexual. I definitely know that I like women it's just that over the past few months I've been having fantasies about a friend of mine who is bisexual. Ever since he came out, I really wanted to have s** with him. It might just be hormones messing with my head I mean sometimes I watch gay porn but after I reach the point of no return I just feel straight again. Can someone please explain to me what's going on?
