I've been to 3 of these. I reviewed one here:

All of the above advice holds true.
My advice:
Get there early. Once you've paid your money strip off, shower and walk around in your towel. He has a separate room with porn on a huge screen for you to enjoy while you wait. When the action starts it'll likely be a sausage fest so don't be too complacent with the other guys. You will get around every girl even if you're not the first.
My first visit I made the mistake of holding off my climax for near the end of the show with my fave girl. I don't do this now. You cant guarantee your best girl will be free when you're ready to pop. So cum when you want. You'll last longer on your second go anyway that way.
Oh and drink lots of water when you're there. You get really hot and tired fucking for so long and there's no window open.
At the end I ask the host for another towel before I shower. Cant guarantee where your original one ended up.
