Just a simple question on orientation exploration?

I'm a guy, 15, and confused and scared about my ual orientation. I like girls and fantasize, ually and non-ually, want to date them, get physically close to them, look at their beautiful faces and bodies etc. I do, however, have interest in a couple of guys. I tend to look at their bodies, and think they're handsome, and like to look at them every once in a while. I've even had fantasies about kissing them, but nothing else, nothing more or less. Is this normal for a teenager because of out of whack hormones and testosterones? Am I too young to make a decision now? is it bad to base uality on fantasies and stuff like that?
