I went to two different high schools. I can say that never happened. My first high school you were REQUIRED to shower after gym class however the showers we stalls with little doors that covered you from about your knees to your neck even still the entire school only had about 22 boys in it (and 40 girls) so when I had gym class there were only 5 other guys 2 of them being my brothers.
The other much larger high school i went to had showers in the locker room but you weren't required to use them for gym class.
I was on the football and swim teams and you did have to shower after practice swim team everyone wore there bathing suits in the shower, in football everyone wore their jockstaps in the shower. I can see why though the shower was a big open room with two pillars that had multiple heads on it. So you were all standing in a circle looking at each other.
