This is a true story.
Last year I was in Europe on business. I had a weekend free there and I had a recommendation from a friend who'd been before to visit a sauna. Not anything seedy you understand; it was a proper upmarket spa sort of place, with saunas, pools, steam rooms, massages, and so on. I'd never been anywhere like that and I was getting bored so I thought it would be fun.
It was a Saturday night in Winter and really cold. There was snow on the ground and I was wrapped up in plenty of layers as I took the bus over from where I was staying on the other side of the city. A short walk from the stop I found the place - a small doorway with a bright sign over it sandwiched in between two fashion boutiques. I went in and up the stairs to a small reception desk with a friendly looking woman in her 50s. She started to speak to me in Swedish, and I used the only Swedish I know to tell her that I had no idea what she was saying. Unfortunately she didn't speak English but I managed to establish that entry was about $50, so I paid and was given a towel and directed through a door into the men's changing rooms.
In there I changed into the shorts I had brought, locked up my clothes and put the key around my wrist. With the towel draped over my arm I made my way up some more stairs and into the main room. It was a really beautiful space on the roof of the building; there was a curved pool dominating the room, two saunas and a steam room down one side, a small restaurant in the corner and plants everywhere. However, what struck me most was that almost everybody but me was totally naked. There were slightly more men than women, but people of all ages and shapes, wandering around totally happily. Some wore towels between the various spaces, but when in the sauna or the pool or on a sunbed they stripped off completely with no regard for who saw them.
Seeing this I must admit that I started to stiffen slightly. I'm stiffening now just remembering it. I thought for a moment and then returned to the changing room. Remembering that I was in a foreign city, where nobody knew me and where this seemed to be the norm, I removed my swimshorts and placed them in my locker with the rest of my clothes. Heading back upstairs with my towel around my waist I took the whole scene in. All around me were nude men and women: some slim, some young, some older and larger, all of them beautiful in their own way. Wary of being caught gawping, I made my way to one of the saunas.
Stepping inside I closed the door behind me and looked around. There were three tiers of wooden seating up either side of the room facing a narrow gap with the door at one end and the coals at the other. The left hand side was empty so I made my way up to the top. I removed my towel and placed it on the bench, and sat on top of it. I, like those around me, was now fully naked. Sweat began to form in tiny droplets on my skin - in the sauna it was easy to blame on the heat, but some of it was the result of sheer arousal.
Across from me were three people. One man sat on the lowest seat, leaning back against the row behind. He was of medium build and must have been about 40. His 5 inch penis rested flacidly to one side on top of his left thigh. His eyes were closed as he soaked up the heat and I just enjoyed watching him for a moment.
