Masturbation-How?

I've had people say to watch stuff or to have the right setting, but no one's actually recommended any techniques. I am horny 24/7 (because I'm sixteen and a virgin) and I've never had an orgasm. I kinda try to just rub, because I don't know what to do. It never gets to a feeling that's great. I really want to have sex, but have no one to do it with and don't want to be considered a slut. Can anyone tell me any techniques or ways to do it other than "just use your fingers"?
