Is it normal that i like watching this more than that?

Ok so I like to mastubate right and see what gets me going is to watch two men kissing or two women. Is this normal and does it mean I'm a lez which I really am not attracted to.girls I have never had sex with a girl.only guys and there were a lot. I never saw or plan myself on ever dating a woman always have and always will be me dating men. So does this mean I could be a lez?
