I've only been to one, and it was quite the ecperience. I think I ended up fucking at least 3 girls and a guy. :) I deffinitly enjoyed myself, but I'd recoment not getting too wasted, you want to be able to tell a pussy from an ass, and the good looking cheerleader from the guy in drag. Also, try to know, in some way, all the people participating. I'm sure you don't want to catch anything. If you can, I'd say go for it!
