I've said it before and I'll say it again- Once you're trans, you're already way beyond queer anyway. Whom I find attractive is all in the noise now. I certainly don't care if I'm labeled "gay". I'm married to a woman, she is my soulmate. I always found women attractive and I never wanted to pursue a guy-guy relationship before I came out. I just never thought anal or oral with a gay guy was for me. I have quite a few gay friends, but I just can't picture having sex with them (nor they with me, I'd assume!)
However, if I was packing a vajayjay, the game changes a bit. I can totally picture having sex with a straight guy if that was the case. I still like girls, but getting stuffed by a fat stiffie suddenly sounds kinda sexy. I could also picture myself with a transguy, transgirl or androgyne.
So I'm sorta pansexual. BFD. I'm queer as all hell and proud of it.
