One of the challenges is to create an equally positive, satisfying sense of femininity and feminine identity in a different way so that there are things you're saying yes to and satisfying that urge that your daughter has to be assert her girlness. The surface level of the culture, and really several inches into it, makes that very hard to do. I hate to put another thing on parents' plates. But the culture is very intentional in what it's telling your daughter and what it's telling you about the message of femininity. And if you're not intentional and conscious back, you lose.

I'm watching my own daughter grow up. I see this overt sexual culture coming at her like a Mack truck. She's in seventh grade.

We continue to think of virginity as first intercourse. That ends up minimizing and marginalizing other things kids are engaged in, like oral sex. And it's not going to feel particularly good for girls as the big marker of adulthood.

Sex-ed courses look at girl's internal parts: for boys it's about ejaculation, erection and wet dreams; for girls, it's periods and unwanted pregnancy. We never talk to girls about sexual self-exploration or self-knowledge.

Intimate justice touches on ideas of gender inequity, violence, bodily integrity, physical and mental health. I don't expect a 15-year-old girl to have that figured out; it's hard enough to have it figured out when you're 50.

While I completely disagree with the "purity" concept, it was the only place I saw fathers talking to girls about their expectations and attitudes to sex and expressing love and support. I didn't see liberal dads having similar conversations with their daughters.

For years we've used the bases analogy - with intercourse being the "ultimate sex" even though that's probably not going to feel good to girls. That model doesn't let you say "I like it at second base, maybe I'll stay here."
