Teens in Louisa County, like teens everywhere, hear a lot about sex, but really know only a little about it. Briana’s Twitter feed is a mix of little-girl cute and grown-woman sexy: a fuzzy kitten, inspirational quotes from Athletes for Christ, an ass in a bow thong. Any senior at Louisa County High School can tick off the names of girls who got pregnant in the past year. But the kids in Louisa County are also part of a generation that’s seen teen pregnancy decline to a record low. Teens are waiting longer to have sex than they did in the recent past. The majority now report that their first sexual experience was with a steady partner. Given how inundated and unfazed they are by sexual imagery, perhaps the best hope is that one day, in the distant future, a naked picture of a girl might simply lose its power to humiliate.
