The nudity concerns me less than what it could lead to. There's nothing inherently shameful or wrong about a human body, but if kids get used to constant nudity, some perv *will* take advantage of it.
when i was in hs, it was weird to be in a boy's locker room for the first time and forced to shower in line(like a conga line) thru the row of showers for a 'rinse off' of gym workout sweat
