Personally shave once a week as it looks and feels better, and must be cleaner. Looking at the hundreds of swingers that expose themselves at VA's, I would say that 99% also shave. Going back a couple of decades, it was quite rare to see lots of shaved pubes in clubs or nudist beaches, and lots of people, including my late wife, felt it a bit strange to consider shaving down there. Attitudes have changed, especially amongst younger adults, with most seeming to want to shave without any thought that it may be anything other than the regular thing to do.
