My name is Luddy, I'm from Brazil, and sorry if there's any English error.
First of all: no one needs to know about your sexuality, I believe that you know this, and I really understand that feeling you have - "I'd like them to know who I really am". It's normal, but not always viable. Be careful.
I know that coming out is scare, but true friends will persist. They will be there for you. And you will sofer because you will be judged. People that you don't even know will judge you. Your parents will probably judge you. You need to be really strong for being gay, mostly, a gay out of the closet - and I don't mean that everyone needs to know about your sexuality just because you're out, but, if you get out and really free, you will probably feel free to say "oh, that guy is hot" even to your straight friends (I do it, I have this freedom, and its priceless). Actually, I'm very discreet (I prefer the term "heteronormative"), so I'm not judged all the time, because no one knows that I'm gay unless if I say it, but the same fear that you have, I already had. I understand you. You are not alone, and never will be if it depends on me.
And your friends probably don't know what it means to use the word "gay" in a bad way. Show them, carefully, what that means. I know that it's hard, mostly in high school, but the reality is the reality, you can't change that. They probably would not use these words if they know you are gay, because they probably like and care about you. Men friendships are mostly dumb, but honest, sincere, and truly beautiful. Maybe, you should talk to the one you trust most or the one that is more open-minded.
If you need to talk to someone, you can send me an e-mail: firstname.lastname@example.org
Hope you will be fine.
