I've seen a lot of posts by naturists (here, but mostly elsewhere) that say that as long as people around them were comfortable with them going nude, then they would, even if it was only them. I'm wondering how common that feeling is and also I think it's a good point to discuss.
For me though, I couldn't do it unless at least a few others also would. If others did though, I would definitely take advantage of it every day. I feel like, even if it's technically allowed and all acceptable, I still need other people to be positive about it rather than just not mind.
