I recently ran into a couple of articles from the 1970's to Dear Abby. in both cases a woman asked about her son wanting to skinny dip in a neighbors pool and with cousins. In both cases the neighbors and cousin's families required the boys in their families to swim nude while the girls (who swam along with them) wore swim suits. The reasons given were it was proper for boys to swim nude; boys should not keep secrets from their sisters and girls are more private. In both instances Abby agreed and said it was fine since these were the accepted rules for the boys to swim in both situations and it gave the girls an opportunity to see what other boy's besides their brothers, looked like.
Although I was pleased and agree with Abby's response i think it would be very different today.
What are your thoughts? Also, did any of you have similar situations growing up or even now; where boys are required/encouraged/accepted to swim nude in mixed company while other family members wore swim suits?
