ERECTION
A public swimming pool I occasionally visit in Covent Garden has open communal showers. Most guys remove their swimwear when showering, meaning there can be up to 8 naked men showering in close proximity. I nearly always get a hard-on and love to show it off for all to see. Never has anyone said anything to me, they either ignore it, or enjoy a good look. Occasionally, mine is not the only erection and I have seen some guys having a damn good play with themselves. HOT!
I can really relate to your post. I often get a little hard when I'm showering in communal showers,, especially when I'm washing that area. It's one of those awkward things and I the more I'm aware of it the bigger it seems to get! I try to conceal it though - not that easy sometimes.
The old saying:
An unwanted erection is like Einstein's Law of Relativity - the more you think about it the harder i gets.
Yes - a nudist can be an exhibitionist, enjoying showing their nude body to anyone around. I'm probably one myself. Erections happen and can be part of it. But intentionally exhibiting an erection, maybe even playing with it, can be more to do with sex than nudism.
