More times than I can count at the gym I have seen a hot guy on the gym floor only to end up naked by chance with the same guy in the gang showers, sauna, steam room or hot tub.
I have posted these stories before, but I'll do it again here. A guy who I worked with when I was in university started to work out with me at the gym after we knew each other for a couple of months. The first time we worked out, he didn't bring any shower gear with him. I hit the showers anyways because I'm a stinky sweaty mess after working out. The next time we worked out, I headed for the shower only to have him join me a couple of minutes later. It was a large gang shower room with Bradley towers in it. He used the same tower as me, so we were face to face when showering. He was a pretty good looking guy, and we pretty much stacked up the same in the cock department. From that point on, we showered together regularly after working out, so it became quite normal until he graduated from university (he graduated 1.5 years before I did). When we travelled through Europe together, we saw each other naked daily because we were sharing accomodations and often slept together in the same bed.
Another time was with one of my fraternity brothers. He was a total pretty boy, and we used to tease him about it all of the time. He would never shower at the gym though after a workout, and I was getting curious to see what he was packing because he was so stunningly good looking. I remember the first time I met him when we were pledging together. I couldn't believe how insanely good looking this guy was. A couple of years after we finished university, I went to visit him in his hometown for a night of drinking on the town. We decided to go for a workout at his local Y. He was going to shower at home, but I convinced him to shower at the Y to save time. Truth be told, I was still curious as fuck to see what he was packing. He agreed. I was quite surprised how easily he just peeled off his clothes at our lockers and walked naked to the sauna. He didn't seem nervous about it at all like I expected him to be. We used the sauna together and then hit the gang shower. I showered across from him, so I got a good view of everything. Again, we pretty much stacked up the same in the cock department, so my curiosity was satisfied. I have always been relaxed about nudity around my male friends. Some of them used to joke with me that I was always naked. I didn't mind because it was true. I feel being nude with your buds is a great bonding moment.
