Gay and straight people alike list all these as reasons why they prefer gay clubs. The anything-goes atmosphere makes for a more pleasant experience. I've never ever seen a fight in a gay bar as long as I've been going, and I've been to gay bars in Miami, New York, Seattle, San Francisco. And then there are the drugs. Ecstasy, speed, mushrooms, whatever you like.
People are there to take the drugs and dance and just feel good.
Dan says the drugs act as a lubricant for meeting people. That wouldn't change if you were or weren't on drugs. Of course, for those who use drugs, discretion is a must. With drugs and so on, we obviously discourage that on the premises, yet we are realists. Of course, it's impossible to discuss straight men who go to gay clubs without bringing up the touchy subject of closeted homosexuality.
