Every day in basic training 37 years ago. Platoon of 80 guys rushing to shower at the same time at the gym while DIs ran around on top of lockers banging metal garbage can lids. You didn't have much time to think about being nude also. Though I still noticed the truly impressive ones and the really not so impressive ones that made me feel a bit better being nude. Fast forward a few months to basic trades training in the Air Force. Would have to take showers after PT class, same large communal type showers but now a lot more relaxed. Usually 50 plus guys at the same time. Had time to check out other cocks with not so much stress. Remember seeing only 2 guys larger than my best friend and roommate. One was a guy from Fiji, truly a freakishly big, what looked to be near 7 to 8 inches soft. I was am more of a grower, 6 x 6, so I just blended in with the normal looking sizes. Also remembered seeing a couple of incredibly small cocks, basically just a small head, no shaft or anything. One was married with kids, really had me scratching my head? Have to say if a person is truly interested in checking out a large number of nude guys at the same time then joining the military is a good idea. I am not gay and not attracted to men per say, just interested in other cocks. I see there is a large number of guys here with the same interest but not really attracted to men.
