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.

But it is Bella, not the supernaturals she falls in with, who is the true horror show here, at least as a female role model.

I found that in a perverse way our culture and parents are far more comfortable talking about girls' vicitimization than girls' sexual agency.

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.

Sexualization is imposed from the outside as opposed to sexuality, an understanding of the body's responses and desires and ability to communicate that, cultivated from within.

Girls would say: "I have a boyfriend for that." So in addition to putting their pleasure literally into someone else's hands - an inept teenage boy - these are the same girls who say they do not climax with a partner. It's the opposite with boys; they say because they can do that themselves, girls should perform oral 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."
