Almost because you're a girl doesn't mean you have to dress up and it doesn't mean that if you're a boy you have to weld a sword.
remember that you're you and you have your own way of thinking, looks, and like.
if you want to weld a sword then weld it, if you want to dress up then dress up, if you love or like someone then you love and like him/her, Gender doesn't matter as long as you're you.
but remember that sometimes you need to change something if that something is that terrible.
and if you're gay or lesbian then you're a gay or lesbian, you're a living person anyway
