I agree. The way you feel now is going to be totally different from the way you feel at say 20 years old. It's pretty common at your age to experiment or question your sexuality among other things. Try to find some healthy things to keep you busy and fulfilled like sports or volunteer work, and try to just relax and enjoy being 12 years old right now. Best wishes.
your 12. your views on pretty much everything are likely to change. either way your not allowed to have a sex change for years. enjoy being 12
