have to do with being "gay"?

TV Surfer has intimated that I'm gay, which raised this interesting question.

Does discussion of a T-Girl's genetalia mean that someone showing a passive or active interest is gay?

From my standpoint:

The girls on this forum that we discuss all have male genetalia. But they appear to be women from all other perspectives.
I've never been sexually attracted to a man and have no desire to see or discuss a man's gentalia, and yet on T-Girls therse male appendages seem to take on an entirely differently spin.
Whatever my interest is in T-girls, I neither have nor will ever have the desire to have one fuck me, that is certain, but I do find the more passible T-Girls sexually attractive.

Aside from TV Surfer, who else here feels that anyone sexually attracted to a T-Girl is gay?
