I'm transitioning because I want to be happy with myself. I hate the body I'm in for many different reasons and I know what I need to do to change that.
There are parts of myself that I love, and I am sculpting those in such a way that they don't get lost with transition, like the fact that I LOVE my butt, I don't want it to get smaller because I love being a guy with a big behind. I like being pretty (to those who consider me such) and I love the fact that being on testosterone hasn't changed that, I'm just a pretty guy instead of a pretty girl now.
I hate my body shape, the sexual organs inside of me, my breasts and my genetic disposition to weight issues and muscle degradation. I want to love my body so part of my transition is toning up and fighting the fat monster to prove to myself and my family that I can beat our genetics to some extent.
