A T-Gurl party is one where all the trans people, vestite, gender and sexual, plus the c/ds get together with their admirers to socialize and possibly (hopefully) have sex. There is one on Thursdays at Isis. As one who has only recently dipped a toe into this world, I have found people to be very helpful and accepting.
My experience is that sexuality has a fluidity that makes labels difficult. I started as a straight guy, had good relationships with women ,batted homo feelings away like flies for a few years before declaring myself to be bi. That eventually morphed to gay and I lived a number of years as a big butch gay man. Now I'm in a phase where I'm getting in touch with my feminine side. I still want to have sex with men, but while dressed as a woman. Increasingly I want a woman in the mix. So does that make me bi? Or, given that I want to do this dressed as a woman, does that make me a lesbian wannabe?
The insistance that we label ourselves based on sexual behavior is limiting and damaging. I think the ones most harmed by this are straight men who want to step slightly outside the accepted norms of male heterosexual behavior.
So, for the op, my suggestion is to be very gentle with yourself. Take the worthwhile advice that you find on here and disregard the bullshit. When you're ready to go to a cruising area, cinema or T-gurl party do so. Remember to keep breathing.
