Does this mean I'm gay?

You shouldn't label yourself until your completely sure. Puberty can be a confusing time where things that never turned you on all of the sudden do now. Trust me when I say, You'll know when the time is right. You should try and experiment to see where your feelings stand. And if you find yourself being attracted to men you can be gay or bi. But I'd lay off the titles and just experiment if I were you. And some anti-depressant side effects are enhanced ual behavior. I took them and I was always horny.
