Can't stop myself from wondering if other people are also gay

This really affects my life. When I see someone kinda feminine or likes something that is usually interested by gays, I always feel questionable if they are gay, if they not i feel like they definitely hide or something. I can even check authors while research articles, googling them if they might be handsome OR gay or not.I think I still can't accept myself about being in minority. I always seek someone gay around. I mean gay friend, not meaning love or stuff. I don't know how I should change the way I think...
