In my view, the ideal scenario for showering after Phy Ed classes would be a boys' locker room where male students have the choice of either using communal "gang"-style showers or individual shower stalls. Ditto for adult gyms and fitness clubs. My middle school locker room had both. I'll bet you the breakdown would be about half & half -- yes, even amongst Millennials and Zoomers. Plus, if homosexuality wasn't so stigmatized by certain religions or some secular voices, I believe that more young and adolescent boys would be a lot more comfortable being open around one another from the get-go.
