For several summers my wife and I enjoyed a set of hot springs down the west side of the Sangre de Cristo mts in Colorado. At the bottom was a locker room shared by men, women, children, seniors for leaving clothing before choosing a pool to soak nude in. Nobody complained about being seeing the other sex naked. What's all the fuss about boys and girls sharing bathrooms? I have seen women using men's rooms at National Parks and at rock concerts.. No biggie.
