Woo boy...that's a tricky one. I remember always hating being given girl's things when I was little. I wanted the trucks and the action figures and the cool water guns. Gender wasn't an issue for me when I was young...I just
was. I knew what I liked and went for it. As I got older, I just refused the gender classification. I felt so misplaced from my peers (the girls playing with silly dolls, the boys refusing to let you join them because you were a girl...grr!) that I convinced myself that I was neutral. I was a nothing. I've dressed and behaved by that code ever since.
There were several times when I was a teenager that I thought about ->-bleeped-<-. I even researched it and the effects of T, the various surgeries possible....But back then, I never imagined it could apply to me. I just thought I was a freak there was no helping, lol. There were also a ton of issues then that...well...made me utterly hate humanity as a whole and retreat into myself. I actually don't remember most of High School. ^_^;
It's only very recently that I've realized just why I've hated myself, my body, the role my family tries to force me into,
everything so much. Literally, it was like putting glasses on for the first time, and finally seeing everything you already saw, only clearly. Everything clicked.
I'm a guy, simple as that.
Oh..er...in response to the actual question...age 26!
