To me it depends on the age of the children involved. I never minded being naked in the bath with my small children, nieces etc. nor do I mind changing with other women and girls at the swimming baths, but I would feel uncomfortable if my 40 year old daughter in law walked into our bedroom while I was naked, or I into hers. I wouldn't want to see my son in his nothingness now either.
Last time I took a class of twelve year old girls to the public bath, it didn't bother me that they saw me naked while showering, but with all the hoo-ha these days about inappropriate behaviour between adults and children, I kept strict custody of my eyes, in the sense the mother superior of my childhood would have approved of.
