Dont get well with other gay people.

I'm 27 now and I'm being openly gay, except for my family, since I was 20. I had always being more masculine and made friends in Highschool with the straight guys, but they're cool and a bunch of nerds that I love. My first gay friend and I guess the only one till today went to a club with me and we kinda hook up that one time and became best friends, but now he moved away.Since him I never get used to gay groups and never make sincere friends. All the other gay dudes I know is because we hooked up or work with me. I think I don't trust or just don't see other gay guys as friends and just get close to then cause I want to hook up.Help me? I want to know if someone had similar experience or have the same difficult.
