this "nude swimming" thing has come up before in forum threads.....
maybe I'm a bit too young, but I NEVER EVER have heard of required nudity in Y/public/school pools.....we swam at public/club pools as kids during the summer, of course, and under those big tent structures in the winter, but they were always just regular co-ed family affairs......we were in the Y, but maybe it didn't have a pool??.....I learned to swim at about four years old and think I wore a suit??!!......I don't think any of my schools before college had a pool used during regular PE......
