If you come to the bay area, more than likely, you will perform with some gay fans in the crowd. Maybe some dont come out and put it out like that, but they are regular people too and they like music.
If you go to a gay club.. its gonna be mixed with lesbians and guys... some guys are feminine that they act like girls. I work in SF at a couple Medical centers and Its a trip with people.. some are openly gay, some act gay, some are metro sexual.. and some you just dont even think at all are gay. My co worker Samantha.. hot ass chick, nice curbs and sexy.. very friendly.. when we connected on facebook... I see her pix with another girl making out doing couples type photos.. blew my mind!
Most of the gay people I know are not the way people think... they hang with their own gay crowd/groups.. and they dont hit on people that is not in their circle.
