I'm not sure how nude swimming is a sexual issue -- but if we're talking about it I'm glad to join in.
I won't repeat what I've said under 'Nude Swimming Teams' over on the Man to Man topics board; that's where I described my experience having had mandatory nude swimming in college back when that was common. But I did swim for enough years without any clothing that it became the natural and normal way for me to go into the water. Ever since then when going swimming I have chosen to be nude whenever I can. That includes pools, ponds, lakes, rivers and -- best of all -- the ocean. Nothing like having waves breaking on your bare butt!
When you're nude at the ocean you're truly away from everything and have a chance to be part of something much larger. I can remember being excited at the magnificence of a long stretch of beach, secluded by some high cliffs and realizing that Naked Gymrat, having left all sign of membership in civilization, was then part of that natural magnificence -- and by extension, I was magnificent myself. And I can remember early one morning seeing an athletic, muscular young fellow playing like a strong, young horse in the surf near the water's edge, jumping, twisting and playing -- and all he wore was a huge smile! Being nude, he belonged to all ages and was a Universal Man, exulting in his energy, prowess and physicality. He made me so proud to be a human, too!
Well, maybe there is a little bit of sexuality to all this. While jogging nude at the water's edge feeling fully part of the wonders of nature I would frequently find that although my cock was soft I was unconsciously producing some long strands of pre-cum which had to be wiped away now and then. I was happy, both in spirit and body! If you haven't tried a nude day at the seashore, I strongly recommend you find a place to do it. Your manhood will enjoy it!
