When Should You Stop Walking Around in the Buff?

A discussion up for debate at my house nearly every morning, I want to know when you think kids should be shielded from their parents' family jewels.

In some families, nudity is acceptable at any age. A number of conservative folks start hiding their unmentionables when their kids are able to talk and point. For others, the age depends on the gender — naked mama and daughter is OK, but nude dad and teenage daughter is awkward. It can also be influenced by culture.

At what age, if ever, will you shy away from showing it all?
