I'm of the age where group showers after phys ed were the norm for men, and most, but not all of the ladies. I was only a manager for high school sports, but when our teams took the role of the vistors, we were usually relegated to the girls locker room.
From reading notices on the wall, we were given to understand that some schools expected women to shower "in the open" some provided stalls, but often oly at certain times of the month, and some did not expect young women to shower after gym.
The dorms and frat houses i lived in durng college usually had one large "open" shower, but I'm given to understand that stall showers were the rule in almost all the women's dorms, and one school noted in public that as the student body became more feminized during the eighties, the open showers were removed whenm a couple of dormitories were converted.
So I'm just wondering if some of the ladies here will add their observations on how exposure and nudity in groups was dealt with when they were coming of age.
