I'm always the only one naked at home or visiting close friends or family, but as more public events I've been naked at raves
I have 2 friends now that I visit every 3 weeks. The are married in their late 70s. After about 30 minutes I take all my clothes off and chat and drink some beers. The don't get naked but don't mind me naked. If it is very hot in side we go out in the garden. I stay naked and some of the neighbors can see us but say nothing.
Many years ago I was staying at the naturist campsite of Belezy in southern France. One evening they had a band playing jazz and I wandered over towards the clubhouse to listen. There was a crowd listening outside and i joined them. It was raining gently but warm, and I was naked. Most others weren't and some were even wearing raincoats! They looked ridiculous but I was comfortable. One bloke even told me I was "courageous". Raincoats at a nudist campsite? Really?
