My wife and I were at the resort this summer, lounging by a couple we'd never seen before. We started chatting; and they brought up their previous nudist destination, which was clearly a swinger's hangout. Then they started going into more detail about their "spicy" enjoyment of that venue: seeing people "getting down." At that point my wife and I started getting weirded out. We're not prudes, by any means; nor do we really want to discuss sexual encounters at "pseudo-nudist" venues; especially with strangers. Being naked does also make a difference; as we can't tell whether it's socializing naked with us that is fueling their desire to "overshare."
I just don't think it's a good idea; unless it's someone you know very well, and you know they don't have some kind of hidden agenda or designs on your wife or yourself.
