As someone who is not American, I first heard about "purity balls" (eesh, that name) for the first time in 2014. It shocked me that fathers and daughters attend these dances to pledge her "purity" and virginity until she is married, giving her little choice or education on, you know, the importance of her own personal choices. Then I saw this trailer for the documentary "Daddy I Do," which highlights the bigger issue: the serious lack of sexual education in America. Watch filmmaker Cassie Jaye explore the issue in the video below.
