Ever been to the St. Louis Art Museum? Plenty of nude adult statues. Ever see old Life magazines? Pictures of soldiers bathing nude, showing their rears, including other situations with nudes of both sexes. As one who's studied art, we had nude models. Many parents put their very young children together to bathe (my mom did, and my mom was very religious...but no prude). People who are offended by innocent nudity have a serious issue, IMO. So the saggy pants exposing underwear is almost laughable as an issue with me.
