I have found the womens lockers and showers easy enough to manuever without showing anything a MTF wouldn't want seen. Both of the places I have been in a situation to use the womens facilities there have been toilet stalls with plenty of privacy to change out and one of the places I went had pivate dressing areas that had curtains. Both places have curtained showers. It is easy enough to wrap up in a towel and cover everything on your way to the shower. And I do not need to exercise any more modesty than any of the other women.
