I grew up in a country where cubicles are unheard of, showers in gyms are often one big room with several showers and no separation walls, and you’re not supposed to wear anything in a sauna (even if mixed sex).
Because of that, it never occurred to me to use a cubicle or get changed under a towel. Not that I am walking up and down the room naked, but I am naked for a few seconds while putting on my underwear. I’m not bothered and there’s nothing interesting to see (40+, bit overweight, c section overhang, so definitely not trying to show off). I never thought anything of it, but seeing some threads here, I start to wonder if that’s inconsiderate / bad etiquette? I don’t want to make anyone feel uncomfortable using the changing rooms.
YABU - cover up
YANBU - do as you please, I couldn’t care less
