I think I'm gay...

I'm 15, , male, and in high school In a small town is Oregon... I haven't really dated much, I was asked out twice by girls, and we went out. But I didn't really feel anything, at all. It didn't last long. But I know a really nice, sweet guy and it makes me feel, idk, different. Like a sort of longing to be loved, and accepted. I think I might be gay, or at least homo-romantic. Any advice or answers?
