Yeah in a nudist spa once. I went alone but planning to meet my friend there who was also going to be going with someone else I didn’t know. When I arrived I was early so I explored the saunas naked alone, then at some point I found my friend. It was in the steam room, I walked in and found my friend and his other friend sitting together. It’s compulsory to be naked there so of course we all met naked, but I also noticed that the new guy who I had never met was sitting with a rock hard cook pointing up between his legs. I sat down next to him and he was between me and my friend. It was so nice because he just acted totally normal, we quietly chatted a bit, all fully naked and him sitting there with a hard cock completely visible right next to us
