tbh I always thought it was weird to be so casual about showing your body like that, I always hated changing rooms because it was really weird to me... Even as a kid I remember seeing my friends flash each others casually (sometimes even me) and I just thought "wtf is wrong with you, I don't wanna see that"
Back then I was either not awaken sexually or into guys at all so this was definitely not my inner pansexual waking up, I just found casually nudity between the same gender weird af... I mean nowadays, it's the same, I might be pan now but I don't just wanna see some random person naked... Shit is weird as hell
