Meredith Chivers is a creator of bonobo pornography.
The bonobo film was part of a series of related experiments she has carried out over the past several years. She showed the short movie to men and women, straight and gay. To the same subjects, she also showed clips of heterosexual sex, male and female homosexual sex, a man masturbating, a woman masturbating, a chiseled man walking naked on a beach and a well-toned woman doing calisthenics in the nude. While the subjects watched on a computer screen, Chivers, who favors high boots and fashionable rectangular glasses, measured their arousal in two ways, objectively and subjectively.
The participants sat in a brown leatherette La-Z-Boy chair in her small lab at the Center for Addiction and Mental Health, a prestigious psychiatric teaching hospital affiliated with the University of Toronto, where Chivers was a postdoctoral fellow and where I first talked with her about her research a few years ago. The genitals of the volunteers were connected to plethysmographs — for the men, an apparatus that fits over the penis and gauges its swelling; for the women, a little plastic probe that sits in the vagina and, by bouncing light off the vaginal walls, measures genital blood flow.
Women are more interested in sex than you think, studies show
An engorgement of blood spurs a lubricating process called vaginal transudation: the seeping of moisture through the walls. The participants were also given a keypad so that they could rate how aroused they felt. Males who identified themselves as straight swelled while gazing at heterosexual or lesbian sex and while watching the masturbating and exercising women. They were mostly unmoved when the screen displayed only men. Gay males were aroused in the opposite categorical pattern. Any expectation that the animal sex would speak to something primitive within the men seemed to be mistaken; neither straights nor gays were stirred by the bonobos.
And for the male participants, the subjective ratings on the keypad matched the readings of the plethysmograph.
Sex drive: how do men and women compare?
All was different with the women. No matter what their self-proclaimed sexual orientation, they showed, on the whole, strong and swift genital arousal when the screen offered men with men, women with women and women with men. They responded objectively much more to the exercising woman than to the strolling man, and their blood flow rose quickly — and markedly, though to a lesser degree than during all the human scenes except the footage of the ambling, strapping man — as they watched the apes. And with the women, especially the straight women, mind and genitals seemed scarcely to belong to the same person.
During shots of lesbian coupling, heterosexual women reported less excitement than their vaginas indicated; watching gay men, they reported a great deal less; and viewing heterosexual intercourse, they reported much more. Among the lesbian volunteers, the two readings converged when women appeared on the screen. But when the films featured only men, the lesbians reported less engagement than the plethysmograph recorded.
Whether straight or gay, the women claimed almost no arousal whatsoever while staring at the bonobos. Full of scientific exuberance, Chivers has struggled to make sense of her data. She struggled when we first spoke in Toronto, and she struggled, unflagging, as we sat last October in her university office in Kingston, a room she keeps spare to help her mind stay clear to contemplate the intricacies of the erotic.
The cinder-block walls are unadorned except for three photographs she took of a temple in India featuring carvings of an entwined couple, an orgy and a man copulating with a horse. She has been pondering sexuality, she recalled, since the age of 5 or 6, when she ruminated over a particular kiss, one she still remembers vividly, between her parents. And she has been discussing sex without much restraint, she said, laughing, at least since the age of 15 or 16, when, for a few male classmates who hoped to please their girlfriends, she drew a picture and clarified the location of the clitoris.
Inwhen she worked as an assistant to a sexologist at the Center for Addiction and Mental Health, then called the Clarke Institute of Psychiatry, she found herself the only woman on a floor of researchers investigating male sexual preferences and what are known as paraphilias — erotic desires that fall far outside the norm. Who am I to study women, when I am a man? But the discipline remains male-dominated.
But soon the AIDS epidemic engulfed the attention of the field, putting a priority on prevention and making desire not an emotion to explore but an element to be feared, a source of epidemiological disaster.
One study, for instance, published this month in the journal Evolution and Human Behavior by the Kinsey Institute psychologist Heather Rupp, uses magnetic resonance imaging to show that, during the hormonal shifts of ovulation, certain brain regions in heterosexual women are more intensely activated by male faces with especially masculine features. Intriguing glimmers have come not only from female scientists.
Richard Lippa, a psychologist at California State University, Fullerton, has employed surveys of thousands of subjects to demonstrate over the past few years that while men with high sex drives report an even more polarized pattern of attraction than most males to women for heterosexuals and to men for homosexualsin women the opposite is generally true: the higher the drive, the greater the attraction to both sexes, though this may not be so for lesbians.
Investigating the culmination of female desire, Barry Komisaruk, a neuroscientist at Rutgers University, has subjects bring themselves to orgasm while lying with their he in an fM. But Chivers, with plenty of self-doubting humor, told me that she hopes one day to develop a scientifically supported model to explain female sexual response, though she wrestles, for the moment, with the preliminary bits of perplexing evidence she has collected — with the question, first, of why women are aroused physiologically by such a wider range of stimuli than men.
Are men simply more inhibited, more constrained by the bounds of culture? Chivers has tried to eliminate this explanation by including male-to-female transsexuals as subjects in one of her series of experiments one that showed only human sex.

These trans women, both those who were heterosexual and those who were homosexual, responded genitally and subjectively in categorical ways. They responded like men. This seemed to point to an inborn system of arousal. Still, she spoke about a recent study by one of her mentors, Michael Bailey, a sexologist at Northwestern University: while fM. Early from a similar Bailey study with female subjects suggest the same absence of suppression.

For Chivers, this bolsters the possibility that the distinctions in her data between men and women — including the divergence in women between objective and subjective responses, between body and mind — arise from innate factors rather than forces of culture. One manifestation of this split has come in experimental attempts to use Viagra-like drugs to treat women who complain of deficient desire. By some estimates, 30 percent of women fall into this category, though plenty of sexologists argue that pharmaceutical companies have managed to drive up the figures as a way of generating awareness and demand.
Desire, it seems, is usually in steady supply. In women, though, the main difficulty appears to be in the mind, not the body, so the physiological effects of the drugs have proved irrelevant. As with other such drugs, one worry was that it would dull the libido. Yet in early trials, while it showed little promise for relieving depression, it left female — but not male — subjects feeling increased lust.
Testosterone, so vital to male libido, appears crucial to females as well, and in drug trials involving postmenopausal women, testosterone patches have increased sexual activity. For the discord, in women, between the body and the mind, she has deliberated over all sorts of explanations, the simplest being anatomy. The penis is external, its reactions more readily perceived and pressing upon consciousness. Women might more likely have grown up, for reasons of both bodily architecture and culture — and here was culture again, undercutting clarity — with a dimmer awareness of the erotic messages of their genitals.
Chivers said she has considered, too, research suggesting that men are better able than women to perceive increases in heart rate at moments of heightened stress and that men may rely more on such physiological als to define their emotional states, while women depend more on situational cues. So there are hints, she told me, that the disparity between the objective and the subjective might exist, for women, in areas other than sex.
And this disconnection, according to yet another study she mentioned, is accentuated in women with acutely negative feelings about their own bodies. Lust, in this formulation, resides in the subjective, the cognitive; physiological arousal reveals little about desire. Besides the bonobos, a body of evidence involving rape has influenced her construction of separate systems. She has confronted clinical research reporting not only genital arousal but also the occasional occurrence of orgasm during sexual assault. And she has recalled her own experience as a therapist with victims who recounted these physical responses.
She is familiar, as well, with the preliminary of a laboratory study showing surges of vaginal blood flow as subjects listen to descriptions of rape scenes. So, in an attempt to understand arousal in the context of unwanted sex, Chivers, like a handful of other sexologists, has arrived at an evolutionary hypothesis that stresses the difference between reflexive sexual readiness and desire. Ancestral women who did not show an automatic vaginal response to sexual cues may have been more likely to experience injuries during unwanted vaginal penetration that resulted in illness, infertility or even death, and thus would be less likely to have passed on this trait to their offspring.
And she wondered if the theory explained why heterosexual women responded genitally more to the exercising woman than to the ambling man.

You need something complementary. That receptivity element. The study Chivers is working on now tries to re-examine the of her earlier research, to investigate, with audiotaped stories rather than filmed scenes, the apparent rudderlessness of female arousal. But it will offer too a glimpse into the role of relationships in female eros. Chivers is perpetually devising experiments to perform in the future, and one would test how tightly linked the system of arousal is to the mechanisms of desire.
She would like to follow the sexual behavior of women in the days after they are exposed to stimuli in her lab. If stimuli that cause physiological response — but that do not elicit a positive rating on the keypad — lead to increased erotic fantasies, masturbation or sexual activity with a partner, then she could deduce a tight link.
Though women may not want, in reality, what such stimuli present, Chivers could begin to infer that what is judged unappealing does, nevertheless, turn women on. The relationship with DeGeneres ended after two years, and Heche went on to marry a man.
After 12 years together, the pair separated and Cypher — like Heche — has returned to heterosexual relationships. Diamond is a tireless researcher. The study that led to her book has been going on for more than 10 years. During that time, she has followed the erotic attractions of nearly young women who, at the start of her work, identified themselves as either lesbian or bisexual or refused a label.
From her analysis of the many shifts they made between sexual identities and from their detailed descriptions of their erotic lives, Diamond argues that for her participants, and quite possibly for women on the whole, desire is malleable, that it cannot be captured by asking women to categorize their attractions at any single point, that to do so is to apply a male paradigm of more fixed sexual orientation.
Among the women in her group who called themselves lesbian, to take one bit of the evidence she assembles to back her ideas, just one-third reported attraction solely to women as her research unfolded. And with the other two-thirds, the explanation for their periodic attraction to men was not a cultural pressure to conform but rather a genuine desire.
She acknowledged this. But she emphasized that the pattern for her group over the years, both in the changing they chose and in the stories they told, was toward an increased sense of malleability. If female eros found its true expression over the course of her long research, then flexibility is embedded in the nature of female desire. One reason for this phenomenon, she suggests, may be found in oxytocin, a neurotransmitter unique to mammalian brains. For Diamond, all of this helps to explain why, in women, the link between intimacy and desire is especially potent.
She is now formulating an explanatory model of female desire that will appear later this year in Annual Review of Sex Research. She spun numerous Hula-Hoops around her minimal waist and was hoisted by a cable high above the audience, where she spread her legs wider than seemed humanly possible. The male, without an erection, is announcing a lack of arousal.
The critical part played by being desired, Julia Heiman observed, is an emerging theme in the current study of female sexuality.
