Not exactly on the theme of restrooms, but I can comment on saunas. I've been to Finland a few times and the gazing culture is much, much different there. Finns are well-known among Europeans as being especially comfortable with nudity and this was absolutely my experience. Helsinki has a number of large public saunas and one, Allas Sea Pool, also has a large outdoor heated pool. In Finnish culture it is not hygienic to use sauna while dirty or clothed and also expected that you shower before swimming. Allas Sea Pool is often frequented by younger people (20s-30s) and from my American perspective, the locker room like a porn. Naked guys close together packing their belongings into small 18" x 18" lockers. Then walking over to gang showers to spray down. Then sitting naked in sauna (only a towel to sit on so you don't burn) and then walking naked back to locker to get trunks before swimming outside. After swimming, the scene repeats. I found that gazing was completely normal - it's just a naked body. Perhaps something sexual happens there but it seemed it was just guys becoming comfortable. People would watch (not stare) others undress, shower, change. Most Finns are light brown or blond and I'm very hairy with dark brown chest hair - I got lots of stares as I was a little different. Similarly, virtually 100% of Finns are uncut and I got lots of stares for being one of the few circumcised guys. A few guys seemed like they'd never seen a cut cock and the guy next to me - seeing my darker hair and cock - asked me "how's your visit to Finland". Just guys being guys. Not that I wouldn't have loved to binge on some Finnish uncut cock...
