I was reminded by the story of the Nairobi friend of an experience I had in an upscale Nairobi Hotel a few years ago.
I visited the sauna when I could in the evening. It was an interesting place with a number of native men lying on cots nude after steam or sauna with women walking around providing towels etc. All these men were very obviously circumcised, I am not and I found it so different from the saunas in Europe where I fit in. While in the sauna, a young airline flight attendant from GB came in. He also was intact and quite nice with about a half hard cock. I was almost hard and he reached over and gave me a couple of quick strokes bringing on a full hard. About that time, another guy came in so we did no more. I indicated I had to leave to meet someone for dinner. He asked which room I was in and I told him.
Later in the evening after I was nude and ready for bed, there was a light knock on the door and it was the flight attendant! I partially opened the door and told him I was nude and he said good! and came in. He quickly undressed and was hard already as was I. He had a very tight foreskin and I showed him how I had my frenulum trimmed and had completely released my foreskin- we jacked each other and both shot into a hand towel quickly then continued until we both shot again. He returned to his room and I never saw him again but often think of the experience.
