Showering in your underwear?!?
I guess the times have changed from when I was in my freshman year gym class in high school in the 70's. All the students were freshmen males. A couple of upperclassmen acted as assistants to the football coach/gym teacher. The coach and assistants watched you shower and inspected you afterwards to make sure you had washed under your arms and had a clean ass crack and asshole. You had to show your white towel stepping out of the shower room and dry off in front off a coach/assistants who approved that you had washed under your arms, behind your ears, and your groin. For the ass area, you had to run the towel up and down between your butt cheeks and rub your anus. The towel was supposed to be white. If the towel was soiled, you were sent back to shower go repeat the process. In the next gym class, your punishment was to run 10 laps in the gym wearing just your required white jockstrap and sneakers...no white short gym shorts or white t-shirt. It didn't happen often but when it did, it was the talk of the school. My parents would have been horrified to hear from the school that I didn't know how to shower properly.
At this point in time, with virtually everyone having a smartphone, I can see how younger guys might be hesitant to peacock in a locker room knowing that someone could take a photo and send it around on social media platforms without your knowledge or consent and upend your life. That kind of scenario is very plausible and scary today.
