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.

My kind of nightmare quote is from Deborah Tolman, who does research on girls and desire and is, I think, brilliant. She told me that by the time girls are teenagers, when she asks them how sexual experience made them feel, they respond by how they think they looked; they think that how they look is how they feel.

Mothers are doing a better job talking about risk, danger, reproduction, consent, unwanted pregnancy. We're not talking about how to balance the risks and joys and we're really not talking about the joys.

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.

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."

Marketing to girls constantly presents a hypersexualized idea of girls; they're expected to appear sexy but be cut off from their sexuality.

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.
