this sounds utterly disgusting, and not in a good way.
I mean, these things are all great in concept but it's been my experience that the kind of people that go to things like swinger parties and sex clubs and kinkfests are all hideous and should only ever be viewed naked by other people that are equally hideous.
Basically, the pretty people don't have to go to big events to seek out partners, because partners seek them out.
That said, if you learned any knots that are more useful for that sort of thing than the basic bowline I might be interested in them.
