Just come out of that closet you've been hiding in since Jr. High. Sure, it'll give the bullies another thing to use against you, but they're already being assholes and you've put them in their place before. Being open about this will probably make you happier and besides, some people have already guessed it. Also, do your fucking homework you lazy ass.
EDIT: Oh, and don't fail PE three times. Having a senior year 2.0 filled with three PE classes back-to-back isn't that fun.
