Adult nudity is one thing, but what about the children?
Prior to the late 198os, research on the effects of parental nudity on children was scarce. Meanwhile, horror stories of nudist-twisted young minds abounded. But according to UCLA psychology professor Paul Abramson, who co-authored an 18-year study on parental nudity, there's no evidence of any harm stemming from parental nudity.
In fact, as discussed in this Quest article, studies have generally associated nudity with beneficial outcomes, such as increased self-esteem, sexual knowledge, lower rates of theft and drug use in adolescence and improved relations with adults outside the family -- as well as increased comfort with physical and emotional intimacy as adults.
