fuck.

I am attracted to a guy, no one knows I am gay, I don't know if he is gay or straight or what, and I don't have the balls to tell anyone anything.

Don't worry about it. You'll find someone to fuck and be around fairly easily. There are probably a bunch of fag0tz in your school or whatever so you aren't alone with it. If one guy you're attracted to turns out not to be gay it doesn't matter, in a month or whatever you might find someone who is and who likes you.
