Diamond doesn’t claim that women are without innate sexual orientations. But she sees significance in the fact that many of her subjects agreed with the statement “I’m the kind of person who becomes physically attracted to the person rather than their gender.” For her participants, for the well-known women she lists at the start of her book and for women on average, she stresses that desire often emerges so compellingly from emotional closeness that innate orientations can be overridden. This may not always affect women’s behavior — — the overriding may not frequently impel heterosexual women into lesbian relationships –— but it can redirect erotic attraction. One reason for this phenomenon, she suggests, may be found in oxytocin, a neurotransmitter unique to mammalian brains…

A symbolic scene ran through Meana’s talk of female lust: a woman pinned against an alley wall, being ravished. Here, in Meana’s vision, was an emblem of female heat. The ravisher is so overcome by a craving focused on this particular woman that he cannot contain himself; he transgresses societal codes in order to seize her, and she, feeling herself to be the unique object of his desire, is electrified by her own reactive charge and surrenders. Meana apologized for the regressive, anti-feminist sound of the scene.

Yet while Meana minimized the role of relationships in stoking desire, she didn’t dispense with the sexual relevance, for women, of being cared for and protected. “What women want is a real dilemma,” she said. Earlier, she showed me, as a joke, a photograph of two control panels, one representing the workings of male desire, the second, female, the first with only a simple on-off switch, the second with countless knobs. “Women want to be thrown up against a wall but not truly endangered. Women want a caveman and caring. If I had to pick an actor who embodies all the qualities, all the contradictions, it would be Denzel Washington. He communicates that kind of power and that he is a good man.”
