Not that long ago, the idea of feeding your kid with organic fruit and vegetables or paying attention to sustainability or any of that - that was very fringy. And I guess some people will argue it still is to a degree, but it's kind of mainstream fringy now.

Girls are removing pubic hair before fully having it. They would say I feel cleaner, it's for me, but then they'd say if a boy saw pubic hair down there they'd head for the hills.

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.

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 never expected, when I had a daughter, that one of my most important jobs would be to protect her childhood from becoming a marketers' land grab.

I asked a high school girl about unreciprocated oral sex and said, "What if guys were asking you to get them a glass of water and never offered to you a glass of water? Would you put up with that?" She burst out laughing. It never occurred to her.

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.
