Should i be worried to take gym in high school if i'm gay?

I'm kinda scared to be in a locker room full of boys and they'll think that i'll be looking at them undress, because every straight guys nightmare that all gays are secretly out to molest them, and i'm not even like that at all, i just want to mind my own business and not have anyone mess with me, because people constantly are out and in school, but i try to stay strong about it and ignore them, but idk what to do anymore, iv'e never done anything to deserve being treated this way.
