Once many years ago at a lake camp everyone decided to go skinny dipping just as it got dark on a hot night. I stripped totally nude and jumped in the water. I started looking around and the other people all had there underwear on except for one topless girl. I was the only one nude. We all got out of the water and I stayed nude and the others in there underwear. Seems there idea of skinny dipping was different than mine. The all looked at me after and I stayed nude till I went to bed.
When I was younger and at the beach with girls a similar age I was always nude, some of them were nude too, some wore swimwear. For some girls wearing a skimpy bikini felt sexier than just being nude. We'd go skinny dipping in the sea as well as sunbathing together and playing games. There were a lot of memorable moments, some not suitable for this forum, but probably most memorable would be girls who went nude for the first time and loved it so much they just went nude every time after and became good naturist friends. Now I'm older I'm still always nude at the beach and sometimes skinny dip with girls, it's different fun now in a different situation, but still very enjoyable.
Pretty much the same as with others here, back in high school we would “break into” area pools to go skinny dipping. A few guys would go nude however the girls would keep their underwear on
Same for us, we would go to apartment complex pools and swim naked really late at night. All the guys got naked
In my 20's, it was pretty common to get naked in the jacuzzi or pool after a few drinks. You loose all inhibitions.
Never did the nude thing with a group of friends, but I am a nudist and have gone to several nude beaches and resorts, so I guess that counts to some degree.
