Not accepted in the 'gay scene'

Okay so I'm bicurious and it's took me a lot to finally admit this to myself and start to try to work out who I am but I have one major problem, I'm not accepted in the gay scene. I've been to gay bars quite a few times and each time I get the same judgemental looks and comments. Sure I look girly but even if I did come out as a lesbian I would still be the same person and dress the same way.. In a local gay club on Saturday night I was dancing away and a couple of gay guys were saying there was no way I was gay and that I should stick to straight bars. And because of this I get no interest from women as they automatically presume I'm straight - how can I change this perception without changing myself? I'm in a situation where I don't have any experience (I've never been with a women before) so women aren't interested in me but how am I supposed to work this out without experimenting.

In the gay clubs on Saturday night I was looking round and I was shocked at how many women were getting off with one women and then a few minutes later onto the next, is that the way it always is? That's not really my thing if so. I want a lasting faithful relationship with someone who loves me whether that's a male or female.
