The "gay scene" has always been a bit too "extroverted" for me. Also gay people can be just as awful and closeminded as straight people, unfortunately. You'd figure having grown up different and struggling for acceptence/understanding would make you more empathetic, but it doesn't always work out that way.
Bisexuals face a unique challenge, we are effectively "invisible". I'm in an opposite gender relationship, from the outside I appear "straight" but I'm not. If I were to, for some reason, suddenly exit this relationship and enter one with a male I'd be seen as "coming out" and suddenly "gay" but really nothing about the status of my sexual orientation changed. I don't know what the solution is or if there even is a solution to that dilemma, I just wish labels would go away.
