Confusing sexual preferences?

Ok so I'm a normal teenage girl that likes boys. However, I've always had this weird thing lurking in my mind. I'm kind of a tomboy and I connect better with my male friends but not in an unnaturally manly way. I've always wished I had been born a guy but I don't dwell on it or think about sex changes or anything. For some weird reason I'm attracted to homosexual male relationships. They kind of turn me on. I also like being the dominate one in the relationship much like the man should be but I do embrace my femininity. I'm not really attracted to girls but I've always wanted to try out a relationship with them. Could I be a lesbian? I don't feel like one. Are my weird attractions normal in some way? I'm kind of confused.
