I originally put this as a reply to something else you said but it applies here more so I moved my post.
I know your just a kid thus aren't confrontational. But if I was in your position I would pretty ticked off at your parents.
Unlike most Transsexuals you kid are happy with your body. And that's actually the most enviable trait you possess even more than all of your feminine appearance.
Your parents have more of a problem with your body than you do that's just really quite disturbing because that should never be the case, Forcing babies to have Sex change operations is really very screwed up and should be illegal.
Tell them that next time... Your not a normal boy, But you are okay with that and you just wanna do the things you do and they should stop pressuring you to have irreversible surgeries or to act like someone you aren't.
As for you, you shouldn't ever feel you have to appeal to there ideas of what normal is to make them happy it's your body in the end and you have to live with it, not them.
