Is there something wrong with me?

I'm 16 and a sophmore in high school. I've always been very popular in middle school and I've always gotten the girls.... but as soon as I entered high school, I meant a couple gay guys and I started feeling attracted to some of the guys. I dated one guy as an experiment, but I just got creeped out and called it off. Rummor started going around saying that I was gay, and I denied it cuz my parents would have killed me cuz they are hugh s. I'm told that I'm very good looking with a very athletic body, and an out going personality... but ever since i expected that I was gay I've been trying to find a good guy who can treat me right, but i can't ever seem to find a nice guy who wants to commit instead of sleep with me. i constintly blame myself, and im trying so hard to figure out why i can't be happy like the rest of the world.
