It depends on how long people were naked @ first max horny but over time it would be the norm
I got hired to play music at a nudist colony a few times. The first time I was a little nervous I might get a boner. LET ME TELL YOU I found nothing sexual about the experience. I’ve compared it to seeing animals in a “natural” habitat in the zoo. Really changed my perspective. Good gig though. Friendly crowd, good pay, got to play buttass naked, and one time they had a water slide.
More horny in the short term, due to the constant stimulation. But less horny over the long term because we would get used to it.
All I know is I’m not turning my back to anyone at a urinal. I’ll be a stall guy from now on.
Much less i would think. Less mystery. Less ways of revealing parts of a body while concealing other parts.
