Freud would have had a field day with this
Evidently there's something in the U.S. called the "Purity Ball", wherein girls, sometimes as young as 7 years old, pledge to their fathers that they won't have sex until marriage. The fathers, in turn, pledge as the "high-priest" of the family to essentially guard the kid's virginity.

Aside from putting the girl in a cloister, i'd like to know how he proposes to do that. On second thought, i don't want to know. It's kinda creepy to contemplate.
