We had coed classes.. never separated... just separate locker rooms.

We were also not required to shower.. however there were 4 private showers (with locks) that were ONLY available to use if you had your period.. you had to ask for the keys and yes the teachers did keep track... and if you didn't fall right on that perfect 28 day schedule they would tell you that you couldn't use a private shower because obviously it "wasn't your time of the month" - it was stupid, since I'm sure many of you know 28 days isn't how it works for everyone

I rarely showered after gym anyways though - there was usually not enough time.. the 5 minutes they gave us was barely enough time to get back to the locker rooms, change, and go use the toilet if you had to, nevermind shower.
