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.

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.

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.

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.

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.

We're afraid if girls find out sex is pleasurable they'll stop being gatekeepers, they'll go out and have sex.

I talked to a junior in college, and she was fed up. She said, "I'm not doing other girls any favours by faking orgasms and not calling out guys when we're having unequal experiences."
