“This greater erotic plasticity appears to manifest in women's more holistic responses to sexual imagery and thoughts. In 2006, psychologist Meredith Chivers set up an experiment where she sowed a variety of sexual videos to men and women, both straight and gay. The videos included a wide range of possible erotic configurations: man/woman, man/man, woman/woman, lone man masturbating, lone woman masturbating, a muscular guy walking naked on a beach, and a fit woman working out in the nude. To top it all off, she also included a short film clip of bonobos mating.
While her subjects were being subjected by this onslaught of varied eroticism, the had a keypad where they could indicate how turned on they felt. In addition, their genitals were wired up to plethysmographs. Isn't that illegal? Non, a plethysmograph isn't a torture device (or a dinosaur, for that matter). It measures blood flow to the genitals, a surefire indicator that the body is getting ready for love. Think of it as an erotic lie detector.
What did Chivers find? Gay or straight, the men were predictable. The things that turned them on were what you'd expect. The straight guys responded to anything involving naked woman, but were left cold when only men were on display. The gay guys were similarly consistent, though at 180 degrees. And both straight and gay men indicated with the keypad what their genital blood flow was saying. As it turns out, men can think with both heads at once, as long as both are thinking the same thing.
The female subjects, on the other hand, were the very picture of inscrutability. Regardless of sexual orientation, most of them had the plethysmograph's needle twitching over just about everything the saw. Whether the were watching men with men, women with women, the guy on the beach, the woman in the gym, or bonobos in zoo, their genital blood was pumping. But unlike men, many of the women reported (via the keypad) that they weren't turned on. As Daniel Bergner reported on the study in The New York Times, "With the woman... mind and genitals seemed scarcely to belong to the same person". Watching both the lesbians and the gay male couple, the straight women's vaginal blood flow indicated more arousal than they confessed on the keypad. Watching good old-fashioned vanilla heterosexual couplings, everything flipped and they claimed more arousal than their bodies indicated. Straight or gay, the women reported almost no response to the hot bonobo-on-bonobo action, though again, their bodily fonctions suggested they kinda liked it.”
