Does liking shemales make you gay?

[zman]

I dont feel guilty. But, the big problem for me right nowis this. I'm into Genetic girls and transexuals. I've never been with a transexual before, and I really want to. However, the girl I'm dating is amazing, but not so amazing as to just let me have sex with someone elde. We've been together for 4 years now, and I'm feel pretty confident I want to marry her. But, the thing that keeps holding me back is that if I do, I'll prolly never get to fulfill my fantasy...
