Palm Springs has many good nudist resorts, including at least one that is lifestyle / adult friendly, it is called Sea Mountain Inn,
www.taboogardens.com. It is couples only though, not single guys. I have not been. I did spend some time in a strip club in Palm Springs, all the other customers were over 60, and the atmosphere reflected it.
The Legendary Dick Drost, former owner of Naked City LA, moved to Palm Springs, and was running some kind of Naked City thing (e.g. a nudist type resort for single guys, with hired girls) out of a house. But that was several years ago, I am not sure he is still doing so.
