For the last couple months I let it grow out and kept it trimmed. During our stay at a nudist resort last weekend seeing about 75% shaved Smooth I was shocked at how many went that way and I shaved it off that night and felt so much better I was thinking I would be one of the only people there shaved. Havent been going to resorts for to long so that aspect was all new to me.
Everyone has their own preference. I personally dont shave everything smooth. I generally dont have the time to keep up with it and I dont like the prickliness that occurs within 24 hours after shaving.
I just keep everything trimmed up, and before the nude beach I trim everything nice and tidy.
I don't do anything special for being nude - I look the way that I look (isn't that part of being a nudist?).
I use a epilator on my balls, so they stay pretty smooth for over a week, and when it grows back it's just fine hair, not stubble, so not really very noticeable. Pubes, I just let it grow, maybe trim it every once in a while.
