I have always shaved clean so never had to worry as most of my shorts either dont have zippers or never use the zipper because shorts are so short I pull it out the bottom . I usually wear trackies in winter and shorts in summer and never wear underwear .
Oh for me was hiking to a water falls. Lots of people around, and I wore my suit with the lining cut out.
Well after enjoying the water and sliding on the rocks. I looked down and the hole front of my suit was ripped open. Not sure how long it was that way. But everything was out in the open. I turned the suit to the side as far as they could go. But I still had a mile hike back to camp.
Well I am not sure if anyone seen, but this was before we were open to being nudists. Now thinking about it, I should try that again and see what happens. Hmmm
