I often wondered what went on at the men-only baths/saunas, and now I know. My curiosity got the better of me, thankfully!
I knew there was one not far from me, having seen it advertised in the local fringe paper. So I called for the address and off I went.
It was a nondescript building with 3 floors but no identification outside except for the number on the door. I walked through the front door to see a glass partition on top of the counter, with a small opening through which I could talk to the guy on the other side. He said it was 10 bucks for a locker for 4 hours, or 15 for a room for the same time.
I paid for the locker and was let through the door to the side of the counter. I was then handed 2 towels and a lock and told the lockers were just down the hall. I found an unused locker, stripped down, then wrapped a towel around my waist. It was about the size of a small bath towel, just large enough to go around and tuck back in. Then I set off to explore.
I saw several other guys wandering about, all similarly clad. To the side of the lockers was a shower room, so I went in for a quick rinse. I could feel eyes following me as I entered the large, open room and turned on one of the showers. Another guy came in then, and started lathering/stroking himself, with predictable results. He was looking at me, but I wanted to get the feel for the place, so I said "not now, but maybe later." He seemed to take this in stride, and away I went, even though it was tempting to get down on my knees and fill my mouth with his lengthening tool.
On the same floor was a sauna. Entering that I could just see 3 rows of benches around 3 sides of the room, and a few guys here and there. I sat down on a middle bench and let the heat sink in as I got used to the very dim light from the single low wattage bulb. In one corner I saw 2 guys with their hands up each other's towels, enjoying the feeling of having their cocks stroked. Then the guy closest to me got down on a lower bench in front of his buddy, opened the towel and buried his head in the inviting, wide-open crotch.
