An interview with London artist Mr Bingo includes hilarious nuggets:

The most important thing I learned while living as a nudist was that clothes are such a big part of how we immediately assess and judge someone. Without them, people are more reliant on what you say to work out who you are. It’s pretty much the freest state you can be in. In California, I ended up playing a naked game of water polo with some senior naturists. They took the game really seriously and one of them told me off for not knowing the rules. I remember thinking, “We’re naked, hitting a ball over a net, in some water. This is really, really silly; how can you be taking this so seriously?” 

You just want to take the guy out for a beer and listen to his stories all night.
