Hmmm, purity balls huh? It actually sounds like a good idea to me. I am going with the thought that dad isn't some freak of nature. It sounds to me like the dad is taking responsibility for the actions of and behavior of his daughter. I wish more parents would do that. I think a commitment to abstinence for teens is a good idea, although idealistic. I didn't have sex until after I was 19 but it was more having to do with phobia of pregnancy than morals.
