Not unusual in many Asian or other countries either. In Korea, they still have bathhouses, jjimjiibang, where the entire family goes to bathe. Men and women are separate, of course...but going to the bath house with your family is quite normal. Sleeping together, bathing together...why do people always have to sexualize it? 'Skinship' (look it up) isn't about sex either. We need to learn the ways of other cultures. .
