If you look at gay porn your gay, if you jack off to a guy, your gay. Basically just think about this, it's not up to us whether you are gay or not. Then again most people think you are.... Just stop thinking about gay thoughts, and soon enough you'll revert to being the old horny teenager who is going to illegally drink and poke holes in his condom. OMG I JUST REMEMBERED SOMETHING!! If your voice is still kind of high even at 19, you MIGHT be gay. Or get a gay guy to see if your gay.
