Moving from Cincinnati to San Clemente, CA in the mid 80's I was lucky enough to find a condo for rent right near the beach where the surfers park. Better yet, my condo was just across the sidewalk from one of the hot tubs for the complex. Big one that would easily hold 20 or more people. It was surrounded by shrubs so most couldn't see in but through my kitchen window I could see under the shrubs and see quite a bit.
Not only could I occasionally see some from our complex go in later at night and skinny dip and then have sex on the concrete surrounding the water, if it wasn't too late, I would just walk across the sidewalk and help myself to a great show as I walked in quietly and 'accidently' catch them in the act. Couldn't care less about seeing her, but very curious about what he might be packing and was usually pretty pleased with the ones I decided to visit.
San Clemente is just outside the gates of Camp Pendleton Marine Base where hundreds and hundreds of 18-21 yr old young male marines that are sent from all over the US for boot camp. On Friday nights, they would parade past my house right on PCH going into town to let off some steam. Most would wave as they passed and a few would stop to pet the two Dalmatians and strike up a conversation. Especially the ones from smaller farm towns who were not used to all this. Over time I sorta got to know several of them and they would come to my place just to visit. Even bring some friends. They were always open to a case of beer and a dip in the hot tub. Of course that meant they either had to change into a suit I gave them or simply went skinny dipping once we got there. Either way I got to check out these hot young well built 18-20 yr old marines.
Also, I could be out walking my two Damatians in the surfer parking lot as well and run into a lone surfer coming up from the ocean and preparing to change out of his wetsuit. They were almost always very friendly - particularly at night and especially with two friendly Dalmatians. So, standing right next to them as they remove their wet suits and towel dry was not an issue. They were used to changing in front of other guys.
On the evenings that was maybe even chilly, I would offer them a nice warm dip in the hot tub just 25 yrds from where we stood and they would almost always accept. This means I would get to see them as well get totally naked two more times before we would go our own ways.
Sometimes I would even see their trucks and vans still there late at night and would go down to the beach a quiet lesser traveled path only to catch them at water's edge totally naked in the moonlight as they wiggled out of their wetsuits and took a quick naked dip in the ocean. I was back along the wall and under the trees unseen - watching and enjoying. Once in a while I'd make myself known from a distance and two times even joined them in a late night swim.
