So far, the replies are true. During Basic & Advanced Training, there were larger communal showers and we all saw each other naked often. Sadly, there were rumors of “salt peter” being put in the food to avoid erections. And, it was true it seemed more difficult to cum, but that may have been the stressful environment. Once in our duty station there were barracks with 1 or 2 soldiers sharing a room/bathroom unless we were on an exercise then there were shower tents but hardly any time to shower much less anything else. We did once use our night vision goggles to watch a hunky lieutenant shower one night which was fun
