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.
