I believe that people have been conditioned into the wrong gender. I have to work on changing myself because I forced myself to be more feminine when I was younger. I'm a pretty effeminate guy, though, all in all, so it's not too much trouble. I grew up hating my body and the only time I was happy with my body was when guys called me hot, I was so happy. Even though I hated my breasts, I took pictures of them and considered even becoming a prosyitute, even though it disgusted me so, so badly... I didn't value myself at all. Albiet, this is less feminine than it is slutty, etc, but I have purposely learned to walk sexy, talk with a higher, smoother tone, etc. I now train my voice to go low and sound masculine.
Just what I went through.
(I didn't mention that I absolutely HATE frontal sex, virgin, I can't even think about it. It makes me retch and the idea of actually doing it, it makes me feel ill and likely to vomit.)
