I live in Germany and I've figured out that I love to flash others. Fortunately we have coed saunas here and nude is the cultural standard. Yesterday, I went to a swimming pool / sauna and deliberately took a locker on the pool side of the building. I spent several hours in the sauna complex completely naked and came back to the locker room wearing only a towel. As I returned to my locker, two young teen girls came out of the changing rooms wearing their bikinis and began putting their stuff away into a locker a few feet away from mine. Even though you're supposed to use the changing rooms, I dropped my towel and began rummaging around in my locker like I was looking for something. I was almost hard and I could see them looking at me and I could hear them talking about me - something close to "foreigners don't know enough to use the changning rooms". But they still smiled and kept looking even when I made eye contact. After a few minutes, they moved off to the pool. I can't wait to go again!
