Ça a l'air un peu d'un truc de ouf' ce "purity movement" dans certaines régions des US...

"The idea is basically that you, as a father, are supposed to serve as the sole male influence in your daughter's life until she gets married. You "guard her heart (and vagina)" because only you can be trusted with it. Certainly she can't. If God wanted women to be in charge of their genitals or feelings he wouldn't have let them be born in Texas."
