Is anyone else’s friend super comfortable around them nude.

This is a weird question but I’ve (20m) never had a friend (20m) be so comfortable nude around me before, at first it threw me off, but I’ve come to get used to it. I’m American and he’s European so that could be something to do with why he’s comfortable as Europeans don’t care. He’s also an athlete who works out so I know that might do something with it to as most guys in the locker room don’t care. I don’t play sports per se.

I really don’t care but am curious if anyone else’s same sex friends are that comfortable around them naked? Like not just undressing or changing but like shower on the day ft type stuff. (And no sexual attraction to each other either)

I ask because it’s not something I’d usually bring up to anyone I can’t tell if that’s weird or normal to ppl, at least in America I think Europe, no
