Lookie here. They're right, mostly. You're just curious. It's normal to experiment with people of the same sex.
And I always hate it when people say that if you want to have sex with a guy you're gay. When you're a teenager, you just can't do that kind of self-classification. You simply don't know, and you won't know until you're body and brain are done turning themselves inside out. Just give yourself time. In a few years, if you feel like you're attracted to men, then maybe you're bisexual or gay, but don't say if you are or aren't now.
