I am currently pre-T but out to everyone I know except my family. Since my friends have been calling me by male pronouns and I've discovered who I really am, my whole perspective has changed and I feel like I can do everything I ever wanted to do or like. I always had this image of a guy with long hair in a leather jacket listening to metal music. And for all my life without knowing, I tried to look like a metalhead dude but it never worked out because of obvious reasons.
Now that I know someday I will look the way I want, I feel like I am interested in the things I always wanted to fit into (new music, motorcycles, etc).
IMO I believe that once you discover and accept yourself, you know that finally someday you will be the person you always wanted to be and so as a result, you get into all this music and activities that never seemed to fit right with your birth gender. ?
