I know children of swingers.
They didn't and don't seem very appreciative about it, so no.
Though I have seen documentary's on it, it does seem quite free, nude ranches where swingers are not only free to sleep with each other, but they read and sing together with a closeness that can't be found anywhere else, besides an intimate relationship, which is what it basically is, you're close to everyone at the ranch cause odds are you've slept with there wife, or girlfriend, with consent from the guy of course.
But I still wouldn't do it, sounds like fun though.
