What determines appropriateness? Do you see some harm in children reading this book?
Don't European children normally see their parents and siblings naked at home?
Aren't German saunas family venues, with both sexes and all ages entirely nude and unsegregated?
Don't finnish schoolchildren sometimes go with their teachers and schoolmates to the school's sauna, in lieu of gym class?
Don't European children see topless women, and men in micro-Speedo's, at the beach, and naked people on TV? Aren't there topless women in magazine and billboard ads?
Has this resulted in any perceivable harm to the children?
Why are children from sexually open societies less "sexualized," less self-conscious, and less sexually obsessed than American kids? Why do they have less sex at a young age and fewer unwanted pregnancies?
Isn't the forbidden fruit always the most tempting?
At the point the viewer realized it's all just fantasy and doesn't reflect reality. This, of course, depends on a child being already familiar with normal, real sex and sexuality.
Physical or psychological age?
Perhaps the age where it would not be either physically or psychologically harmful.
