I know of a couple clubs in the united states that are members only with similar ideas, but I can't remember where they are off the top of my head... something makes me wanna say one of them is in washington or oregan. I had a soc professor who was a specialist in human sexual behavior ad he talked about a few around the country that he had been invited to, but he said most of them were very reclusive and expensive as they cartered to rich and famous, so i don't know how much information you could find about them on line.
