Tried to look at a guy in locker-room. does this necessarily mean I'm gay, bi?

freshman, 15, guy goes to locker-room with others after archery is over. I try to take a look at him. Not at him naked, gross, just curious to see him, with at least some boxers on. I like girls, but am curious about this guy and another one I asked to kiss but felt pressured (i apologized and everything). you can look at my other question asking whether I was straight or bi. But, does being curious about the same sex make you gay or bi?
