If you're looking to us to tell you whether you're gay or not, then you're not going to get a decent answer. The only person who can really answer that question is you. First off, what makes you think you're gay? IF you've had passing sexual thoughts or dreams that involve same-sex situations, that doesn't make you gay. If you experimented a bit, that doesn't make you gay. Try asking yourself questions like these. Can you see yourself falling in love with another person of the same sex? Can you picture spending the rest of your life with them? Raising a family with them? Picking out a car together? cuddling up together on the couch during a movie? Mixing your laundry with theirs? Buying a house together? Basically, typical "couple" stuff? I don't know what else to say since I don't know anything about you or your situation. Just keep an open mind to all possibilities. If you do that and are honest with yourself, then your true sexuality will reveal itself. Don't try to force yourself to be straight, gay, or bisexual. Sexuality cannot be forced. If it is, then I have to wonder how real it can truly be. Okay, I'm done.
What monosphere has said pretty much explains it. though I have to say that when you're a teen, you're likely to experience this kind of doubts about your sexual preference. It's all normal.
