At some of the larger parties I’ve attended, people wore colored wristbands that would let others know their sexual preferences(blue for straight, green for gay, and yellow for bi). If you are truly interested in getting involved with adult-oriented parties, you might want to check out the ads in the alternate/underground weeklies in your areas. Also, you might Google “(your city), erotic ball”.
That’s a subject for debate, IMHO.
Well…
When a man, a woman, another woman, a few other men, a goat, and a couple midgits love each other very much… 
…and on closer reading, it appears Evil Captor beat me to the punch with that joke. :smack:
And I even took the time to scan the whole thread for any jokes like that because I was sure someone would come up with it faster than that. I don’t know how I missed it.
I recommend Costco for all your bulk towel (and multipacks of KY and condom) needs. Theoretically. I KNOW NOTHING!
Many moons ago when I was a mere sprog I was at an orgy.
There was about 2 dozen of us, male and female, it was a total disaster at least for me.
Why?
My bloody cousin turned up and how I used to respect that girl.
Double standards, you bet 
Another Gay guy checking in.
When I was living in Berlin, there was a guy who was a professional orgy organizer.
He had a large apartment, with one room that was filled with only mattresses.
People would show up at his apartment before the “cut off time” (I believe it was 9 PM) and then he would lock the door.
Then people were told to strip and go into the next room.
He used to have these parties about twice a month - and anywhere from 10 to 50 people would show up.
Oh, and he charged about $5.00 per person, but he did supply the beer and rubbers and other things any good orgy hostess would supply.
Dopefest!
Years ago Brainiac4 and I helped organize a large SF con. I can’t remember if it was us, or if it happened after our time but all the sex parties were on a single floor of the hotel which was restricted to adults. Many of the parties were - apparently - open invite - they put up posters. I avoided it for the most part (I think I may have walked down the hall).
Well, when a band is hard-up for hits, and their corporate manager decides what the world really needs is a lame remake of a New Order song…
