Our PE coach took us 7th graders into town to play track with the other schools. They had a gym and showers, and he took us to shower after the meet. Some of our guys were in the shower with shorts on, some naked, I went in naked, but had a good hard on. They all laughed at me. Later, the older boys came to me privately and said, do not worry about that, all of us get like that. Pay them no attention. In service, I would pull on my cock, to make it appear larger. The ships I was on had public showers, and all of them had semi-hard dicks. One guy, married had one of the largest I have ever seen. Like a horse. We use to make jokes of him, as his young wife was a small woman in statue.
