They were the norm when I was a kid, though that was a long long time ago. I didn't realise they'd have changed. Does everyone have like a separate shower stall now? Because if so, that makes this even more unhinged.

Children don't know that being naked with other people is wrong until we teach them self-loathing. If we just stopped, being naked would be normal and natural and there would be nothing sexual or perverse about it. It's all adult projection of our fear and self-loathing.
