Showers after sports were large (20X20) tiled affairs, with rows of shower heads on each wall, no dividers. In high school, our sports locker rooms, were again, wide open. Locker rooms had no dividers, along with bathrooms and showers. I have been to all men athletic clubs in the 60’s and 70’s where the swimming pools were naked. Having been born in the 50’s, I chuckle at how younger men are not exposed to the experience of being around basically nude men doing normal things.
