Two years ago at Club O. my wife "accidentally" flashed the entire beach while rolling around naked in the surf. A couple of days prior she decided to walk bottomless at night on a public beach.
Last year we went back to St. Martin and she wouldn't be caught nude.
A few days ago we talked about a nudist resort; and I asked her if she wanted to go. She not only said yes; but she was looking forward to hanging out naked.
It truly "comes and goes."
