I think humans are mammals, therefore inherently sexual beings. Any activity engaged in by sexual beings is going to have innate sexual dynamics. I also think we live in a repressive puritanical milieu which taints everything with it's thanatotic poison.
Going to our closest nudist resort soon. Cant wait, but I dont expect to see a hard dick, other than mine.
Merriam-Webster dictionary… “Nudism: the practice of going nude especially in sexually mixed groups and during periods of time spent at specially secluded places.” What isn’t included in that definition is motivation. In the early movement, there was a motivation attached to the definition: Health. Along with that came a restriction, nudity must be non-sexual. It seems the restriction was fanatically enforced regardless of any deviation in thought on the part of any member of the movement. And as humans are prone to individual thought, you can bet that there were those whom did not agree with the official and unnegotiable line. Most things evolve, and so has nudism. There are some who insist that the movement has not evolved and anybody who deviates from the original constrictions simply isn’t a “nudist.” They are correct: In the classical sense many are not. They are wrong: In the modern sense the number of non-traditionally minded nudists is far larger than would be admitted. For me, the motivation to be involved in nudism was entirely about sex. My wife was reluctant at first, but the reluctance ended quickly. There is a broad spectrum of people in nudism, from one end of the extreme to the other. And plenty more in the middle.
My wife and I have a lake cottage that is somewhat isolated and we spend most of our warm weather time naked alone, with each other, or with friends. If I'm alone I never get an erection. If I'm with just my wife I only get erect if we are about to have sex. If I'm with a coed group I never get an erection. If I'm with my wife and female friends I never get an erection. If my wife has to leave the group of female friends to get something from the house, I will get an erection almost immediately. It's amazing how just being naked with females I know well gives me an erection. LOL, no one seems to care. I sure don't!
