Watching gay ..but not gay ?

Hey,im a 14 year old and the other month i watched some gay , just outta curiosity and i kinda liked it. Obviously, i like hetero ALOT aswell. I got quite turned on by it since im quite a big fan of dominatrix However, for me , even thinking of a man naked in real life really disgusts me. I get no nervous feelings or "erflys" around men, like i do with some woman, so i know im not physically attracted to men. This is really confusing me. Whats wrong with me ? Am i really deep down bi ?
