Very cool. I've sometimes wondered if swinging would be a scene I'd enjoy. Unfortunately, I think a major deterrent for me would be the secrecy; I like to connect with people who are glad to be open about the fact that they've chosen to connect with me. Likewise, I don't enjoy the weight of others' secrets. But I do seem to be aging like wine — thus far, at least.... so maybe it's in my DNA. ;)
