I still favor if nudity is shared by all people present. I’m more open-minded, yet, about cloths accompanying their nudist pal or S/O; if they’re cool with me, I am cool with them.
Both scenarios I presented, I also recognize, were a bit unique. In the first, we were a group of nude folks who’d just spent the entire week end entirely bare; and here walks in a completely dressed lady! Which sort of broke up the nude vibe we were all enjoying.
The next situation was genuinely a “chickening out” situation. My pal, or so she said, intended to join me but absolutely froze up ( http://videonudism.com/teen kicked in).
She’d no rational explanation for it; but I believe it’s to do with the whole “easier to be nude among strangers than with a friend/relative” matter. Her daughter came in the picture just a while later, asking why we were not bare; her mother explained that she’d chickened out. Which caused her to also chicken out and return with a bathing suit on!
Ever since then, I’ve discovered myself in an “only nude person in the room” scenario once or even twice. In those scenarios, there did not bother me because those were folks who usually went bare, only not in that particular situation. One was on a chilly morning at the resort; sarongs and T shirts everywhere except me. The way I looked at it: “I didn’t just drive 90 miles to keep my clothes on! No way!” Another time, I was around at a friend’s house and he encouraged me to make myself comfy. Why was that distinct from my second scenario? My nudity did not change him as it’d my pal. No worries; no intrusion? Then no issue.
