Before I transitioned, I was asexual, and gay-acting. I didn't want to get into any relationships because I knew that it would have to be as male, and I knew that sort of thing could never end well. However, it may be noteworthy to say that, during that period of my life, I was attracted to girls. Since then, this has switched; there isn't nearly as much attraction to women as there once was - rather, I strongly prefer men now. It may have been the hormones, or perhaps before transition, I merely didn't explore the issue of men to enough extent to know if I enjoyed them. I don't know.
The gay-acting was just me being me... To be flamboyant was the only way to live - it was fun, and I could enjoy myself a little.
By no means was I a heterosexual male (I transitioned before I could even be called a "man" - not that I would ever call myself such a thing anyway), but I didn't quite fit the archetype of the gay male either. I was just a weirdo.
