Agreed. I don't remember any time where high school showers were presented as something social, communal, soothing. Everyone knew they were embarassing and a place where bullying was particularly vicious.

Meanwhile, when I was really little my father took me to a workout club that was mostly old guys, and they'd all kind of hang out butt ass naked in the locker room, talking about whatever, completely comfortable and unbothered. It was nominally the same - communal bathing, but the absolute opposite vibe.
