It's not clear to me if you are a woman or man, but as a former 15-year-old son, I can assure you: The possibility of a woman walking into the restroom when we are using it is both a) the least of our problems and b) not really that scary whatsoever. I mean, does your 15-year-old leave the house? Because whenever he does, there's a good chance he's doing something WAY more unsafe than sharing a restroom with a lady.
