Creepiness exalted: "Purity balls, Plan B and bad sex policy: inside America's virginity obsession."

Like the Supreme Court justice suggested, one knows obscenity when he or she sees it. The entire notion of a "purity ball" is raincoater creepy.

Purity balls, Plan B and bad sex policy: inside America's virginity obsession, by Jessica Valenti (Guardian)

We are teaching girls that their virginity makes them special. But we're also sending the wrong message – that without their virginity, they're damaged goods

The men and girls in the photos hold hands and embrace – the young women are in long white dresses, the men in suits or military regalia. If some of the girls in the pictures weren't so young - Laila and Maya Sa up there are seven and five years old, respectively - the portraits could be mistaken for wedding or prom pictures. What they actually capture, though, are images of those who participate in purity balls – father-daughter dances featuring girls who pledge to remain virgins until marriage and fathers who promise to protect their daughters' chastity.

The images from Swedish photographer David Magnusson's new book, Purity, are beautiful, disturbing and tell a distinctly American story – a story wherein a girl's virginity is held up as a moral ideal above all else, a story in which the most important characteristic of a young woman is whether or not she is sexually active. This narrative of good girls and bad girls, pure girls and dirty girls, is one that follows young women throughout their lives. Purity balls simply lay that dichotomy bare. In a clip from a Nightline Prime episode on these disconcerting events , a father tells his braces-clad daughter, "You are married to the Lord, and your father is your boyfriend."
