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.

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.

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.

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."

Parents tend to name all of baby boys' body parts, but with girls they go from belly button to knees with this void in the middle. That doesn't change as kids go into puberty.

Sexualization is the performance of sexuality, the performance of sexiness. Girls are super good at that now.
