Mainstream science--as well as religious and cultural institutions--has maintained that men and women evolved in families in which a man's possessions and protection were exchanged for a woman's fertility and fidelity. But this narrative is collapsing. Fewer and fewer couples are getting married, and divorce rates keep climbing as adultery and flagging libido drag down even seemingly solid marriages.How can reality be reconciled with the accepted narrative? It can't be, according to renegade thinkers Christopher Ryan and Cacilda Jethá. While debunking almost everything we "know" about sex, they offer a bold alternative explanation in this provocative and brilliant book.Ryan and Jethá's central contention is that human beings evolved in egalitarian groups that shared food, child care, and, often, sexual partners. Weaving together convergent, frequently overlooked evidence from anthropology, archaeology, primatology, anatomy, and psychosexuality, the authors show how far from human nature monogamy really is. Human beings everywhere and in every era have confronted the same familiar, intimate situations in surprisingly different ways. The authors expose the ancient roots of human sexuality while pointing toward a more optimistic future illuminated by our innate capacities for love, cooperation, and generosity.With intelligence, humor, and wonder, Ryan and Jethá show how our promiscuous past haunts our struggles over monogamy, sexual orientation, and family dynamics. They explore why long-term fidelity can be so difficult for so many; why sexual passion tends to fade even as love deepens; why many middle-aged men risk everything for transient affairs with younger women; why homosexuality persists in the face of standard evolutionary logic; and what the human body reveals about the prehistoric origins of modern sexuality.In the tradition of the best historical and scientific writing, Sex at Dawn unapologetically upends unwarranted assumptions and unfounded conclusions while offering a revolutionary understanding of why we live and love as we do.

    That's taught as fact in psychology textbooks, academic journals, and bestselling books. And these hardwired differences explain everything from sexual orientation to gender identity, to why there aren't more women physicists or more stay-at-home dads.In this compelling book, Rebecca Jordan-Young takes on the evidence that sex differences are hardwired into the brain. Analyzing virtually all published research that supports the claims of "human brain organization theory," Jordan-Young reveals how often these studies fail the standards of science. Even if careful researchers point out the limits of their own studies, other researchers and journalists can easily ignore them because brain organization theory just sounds so right. But if a series of methodological weaknesses, questionable assumptions, inconsistent definitions, and enormous gaps between ambiguous findings and grand conclusions have accumulated through the years, then science isn't scientific at all.Elegantly written, this book argues passionately that the analysis of gender differences deserves far more rigorous, biologically sophisticated science. "The evidence for hormonal sex differentiation of the human brain better resembles a hodge-podge pile than a solid structure... Once we have cleared the rubble, we can begin to build newer, more scientific stories about human development."

    Even though the glass ceiling is cracked, most women stay comfortably beneath it, and everywhere we hear about vitally important “hardwired” differences between male and female brains. The neuroscience we read about in magazines, newspaper articles, books, and sometimes even scientific journals increasingly tells a tale of two brains, and the result is more often than not a validation of the status quo. Women, it seems, are just too intuitive for math, men too focused for housework.Drawing on the latest research in neuroscience and psychology, Cordelia Fine debunks the myth of hardwired differences between men’s and women’s brains, unraveling the evidence behind such claims as men’s brains aren’t wired for empathy, and women’s brains aren’t made to fix cars. She then goes one step further, offering a very different explanation of the dissimilarities between men’s and women’s behavior. Instead of a “male brain” and a “female brain,” Fine gives us a glimpse of plastic, mutable minds that are continuously influenced by cultural assumptions about gender.Delusions of Gender provides us with a much-needed corrective to the belief that men’s and women’s brains are intrinsically different--a belief that, as Fine shows with insight and humor--all too often works to the detriment of ourselves and our society.

    Whether it’s voyeurism, exhibitionism, or your run-of-the-mill foot fetish, we all possess a suite of sexual tastes as unique as our fingerprints—and as secret as the rest of the skeletons we’ve hidden in our closets.Combining cutting-edge studies and critiques of landmark research and conclusions drawn by Sigmund Freud, Alfred Kinsey, and the DSM-5, Bering pulls the curtain back on paraphilias, arguing that sexual deviance is commonplace. Bering confronts hypocrisy, prejudice, and harm as they relate to sexuality on a global scale. Humanizing so-called deviants while at the same time asking serious questions about the differences between thought and action, he presents us with a challenge: to understand that our best hope of solving some of the most troubling problems of our age hinges entirely on the amoral study of sex.

    A distinguished evolutionary biologist, Roughgarden takes on the medical establishment, the Bible, social science—and even Darwin himself. She leads the reader through a fascinating discussion of diversity in gender and sexuality among fish, reptiles, amphibians, birds, and mammals, including primates. Evolution's Rainbow explains how this diversity develops from the action of genes and hormones and how people come to differ from each other in all aspects of body and behavior. Roughgarden reconstructs primary science in light of feminist, gay, and transgender criticism and redefines our understanding of sex, gender, and sexuality. Witty, playful, and daring, this book will revolutionize our understanding of sexuality.Roughgarden argues that principal elements of Darwinian sexual selection theory are false and suggests a new theory that emphasizes social inclusion and control of access to resources and mating opportunity. She disputes a range of scientific and medical concepts, including Wilson's genetic determinism of behavior, evolutionary psychology, the existence of a gay gene, the role of parenting in determining gender identity, and Dawkins's "selfish gene" as the driver of natural selection. She dares social science to respect the agency and rationality of diverse people; shows that many cultures across the world and throughout history accommodate people we label today as lesbian, gay, and transgendered; and calls on the Christian religion to acknowledge the Bible's many passages endorsing diversity in gender and sexuality. Evolution's Rainbow concludes with bold recommendations for improving education in biology, psychology, and medicine; for democratizing genetic engineering and medical practice; and for building a public monument to affirm diversity as one of our nation's defining principles.

    Experienced ethical sluts Dossie Easton and Janet W. Hardy dispel myths and cover all the skills necessary to maintain a successful and responsible polyamorous lifestyle--from self-reflection and honest communication to practicing safe sex and raising a family. Individuals and their partners will learn how to discuss and honor boundaries, resolve conflicts, and to define relationships on their own terms. "I couldn't stop reading it, and I for one identify as an ethical slut. This is a book for anyone interested in creating more pleasure in their lives . . . a complete guide to improving any style of relating, from going steady to having an extended family of sexual friends." --Betty Dodson, PhD, author of Sex for One

    Rather, this is a drop in the ocean, a paddle in the shallow end of sex history, but I hope you will get pleasantly wet nonetheless.The act of sex has not changed since people first worked out what went where, but the ways in which society dictates how sex is culturally understood and performed have varied significantly through the ages. Humans are the only creatures that stigmatise particular sexual practices, and sex remains a deeply divisive issue around the world. Attitudes will change and grow – hopefully for the better – but sex will never be free of stigma or shame unless we acknowledge where it has come from.

    They aren't sexually attracted to anyone, and they consider it a sexual orientation—like gay, straight, or bisexual.Asexuality is the invisible orientation. Most people believe that "everyone" wants sex, that "everyone" understands what it means to be attracted to other people, and that "everyone" wants to date and mate. But that's where asexual people are left out—they don't find other people sexually attractive, and if and when they say so, they are very rarely treated as though that's okay.When an asexual person comes out, alarming reactions regularly follow; loved ones fear that an asexual person is sick, or psychologically warped, or suffering from abuse. Critics confront asexual people with accusations of following a fad, hiding homosexuality, or making excuses for romantic failures. And all of this contributes to a discouraging master narrative: there is no such thing as "asexual." Being an asexual person is a lie or an illness, and it needs to be fixed.In The Invisible Orientation, Julie Sondra Decker outlines what asexuality is, counters misconceptions, provides resources, and puts asexual people's experiences in context as they move through a very sexualized world. It includes information for asexual people to help understand their orientation and what it means for their relationships, as well as tips and facts for those who want to understand their asexual friends and loved ones.

    In lively and impassioned prose, she breaks down three key dualisms - sex/gender, nature/nurture, and real/constructed - and asserts that individuals born as mixtures of male and female exist as one of five natural human variants and, as such, should not be forced to compromise their differences to fit a flawed societal definition of normality.

    The idea of “the heterosexual” was unprecedented. After all, men and women had been having sex, marrying, building families, and sometimes even falling in love for millennia without having any special name for their emotions or acts. Yet, within half a century, “heterosexual” had become a byword for “normal,” enshrined in law, medicine, psychiatry, and the media as a new gold standard for human experience. With an eclectic scope and fascinating detail, Straight tells the eye-opening story of a complex and often contradictory man-made creation that turns out to be anything but straight or narrow.

    Women crave intimacy and emotional connection. Women don't want sex with strangers. Right? Wrong. Could 'the fairer sex' in fact be more sexually aggressive and anarchic than men? In What Do Women Want? Adventures in the Science of Female Desire, critically acclaimed journalist Daniel Bergner looks at the evidence. Recent research, he finds, dismantles the myths to reveal an unprecedented portrait of female lust- the triggers, the fantasies, the mind-body connection (and disconnection), the reasons behind the loss of libido and, most revelatory, that this loss is not inevitable.

    Then she is publicly hanged alongside her attacker. These events took place in 1644, in Boston, where today they would beviewed with horror. How--and when--did such a complete transformation of our culture's attitudes toward sex occur?In The Origins of Sex, Faramerz Dabhoiwala provides a landmark history, one that will revolutionize our understanding of the origins of sexuality in modern Western culture. For millennia, sex had been strictly regulated by the Church, the state, and society, who vigorously and brutally attempted topunish any sex outside of marriage. But by 1800, everything had changed. Drawing on vast research--from canon law to court cases, from novels to pornography, not to mention the diaries and letters of people great and ordinary--Dabhoiwala shows how this dramatic change came about, tracing theinterplay of intellectual trends, religious and cultural shifts, and politics and demographics. The Enlightenment led to the presumption that sex was a private matter; that morality could not be imposed; that men, not women, were the more lustful gender. Moreover, the rise of cities erodedcommunity-based moral policing, and religious divisions undermined both church authority and fear of divine punishment. Sex became a central topic in poetry, drama, and fiction; diarists such as Samuel Pepys obsessed over it. In the 1700s, it became possible for a Church of Scotland leader tocommend complete sexual liberty for both men and women. Arguing that the sexual revolution that really counted occurred long before the cultural movement of the 1960s, Dabhoiwala offers readers an engaging and wholly original look at the Western world's relationship to sex.Deeply researched and powerfully argued, The Origins of Sex is a major work of history.

    However, that's not to say that the Sumerians, Victorians, and every civilization in between and beyond have not tried, wielding their most formidable weapon: the law. At any given point in time, some forms of sex were condoned while others were punished mercilessly. Jump forward or backward a century or two (and often far less than that), and the harmless fun of one time period becomes the gravest crime in another. Sex and Punishment tells the story of the struggle throughout the millennia to regulate the most powerful engine of human behavior.Writer and lawyer Eric Berkowitz uses flesh-and-blood cases—much flesh and even more blood—to evoke the entire sweep of Western sex law, from the savage impalement of an Ancient Mesopotamian adulteress to the imprisonment of Oscar Wilde in 1895 for "gross indecency." The cast of Sex and Punishment is as varied as the forms taken by human desire itself: royal mistresses, gay charioteers, medieval transvestites, lonely goat-lovers, prostitutes of all stripes, London rent boys. Each of them had forbidden sex, and each was judged—and justice, as Berkowitz shows, rarely had much to do with it. With the light touch of a natural storyteller, Berkowitz spins these tales and more, going behind closed doors to reveal the essential history of human desire.

    Since then, Fisher has conducted pioneering brain research on lust, romantic love, and attachment; gathered data on more than 80,000 people to explain why you love who you love; and collected information on more than 30,000 men and women on sexting, hooking up, friends with benefits, and other current trends in courtship and marriage. And she presents a new, scientifically based and optimistic perspective on relationships in our digital age—what she calls “slow love.”This is a cutting-edge tour de force that traces human family life from its origins in Africa over 20 million years ago to the Internet dating sites and bedrooms of today. And it’s got it all: the copulatory gaze and other natural courting ploys; the who, when, where, and why of adultery; love addictions; her discovery of four broad chemically based personality styles and what each seeks in romance; the newest data on worldwide (biologically based) patterns of divorce; how and why men and women think differently; the real story of women, men, and power; the rise—and fall—of the sexual double standard; and what brain science tells us about how to make and keep a happy partnership.

    Doctors loathed this time-consuming procedure and for centuries relied on midwives. Later, they substituted the efficiency of mechanical devices, including the electric vibrator, invented in the 1880s. In The Technology of Orgasm, Rachel Maines offers readers a stimulating, surprising, and often humorous account of hysteria and its treatment throughout the ages, focusing on the development, use, and fall into disrepute of the vibrator as a legitimate medical device.
