In retrospect, I kind of wish it had been mandatory in school. It would have made it a lot easier if everyone had been showering. Even at summer camp, it wasn't required. And we stayed for 1-2 weeks. Fortunately for me, I didn't start going to camp until after my experience at school. When we had the opportunity to shower, I was totally comfortable. When it came time to shower, none of the other guys in my cabin wanted to do it. Some of them even changed clothes under a towel.
I went to the showers by myself the first day. The second day, I was getting ready to go to the shower again. I dared one of the other guys to come with me. He didn't like being called chicken and accepted the dare. In the shower room, I got undressed and turned on the shower. He hung back sort of watching. I made chicken noises and finally he relented, undressed, and came into the shower. The third day, it seemed like I'd be going by myself again. As I was leaving, the guy from the previous day said wait and came with me.
There wasn't much privacy at camp, so I hadn't been able to masturbate since we'd arrived. I got an erection in the shower. The other guy had one too, so I figured he was in the same predicament. I'd masturbated with a few friends before, so I asked him if it would be okay for me to do it. He was a bit taken aback, but said sure. My mom, thankfully, had made sure I packed lube for the trip. I got it out, and went to work. After a minute or so, they other guy asked if he could get some. I gave him the bottle and we both jerked off in the shower. He came first and I went slightly after. We both started laughing after. We showered off and went back to the cabin.
The next day, we both went to the shower again. We were in the shower when the door opened and one of the other guys from our bunk came it. He didn't say anything. He just got undressed and got in the shower. By the end of the first week, all 8 guys from our bunk were showering. We were the only ones at camp.
Towards the end of our second week, we did an overnight camp by the lake. When it came time to swim, the first guy that showered with me dared everyone to skinny dip. The campers all went for it. Our councilor looked panicked at first as we all ran naked into the water. He realized, however, that it wasn't a big deal and eventually joined us. Nobody put their clothes back on until it was time to head back to the main camp.
Our last day at camp, we were all in the shower. A few of the guys had erections. The first guy that showered with me surprised me when he asked if I had any more lube. I gave it to him, and he began to masturbate in the shower. The other guys looked shocked. I figured it was the last day and we should have some fun, so I joined in. The other guys watched us not sure what to do. Then another guy grabbed the lube and started to go to work on himself. Then another, and another. All 8 of us were jerking off. We must have been taking a while, because our councilor came looking for us. His jaw dropped when he saw what was going on. He just told us to hurry up and bolted out of there. We all busted out laughing. We all finished one after another and went back to our bunk.
I never saw most of those guys again, but it was one of the best summers of my life.
