What causes a child to grow up gay or straight? In this book, neuroscientist Simon LeVay summarizes a wealth of scientific evidence that points to one inescapable conclusion: Sexual orientation results primarily from an interaction between genes, sex hormones, and the cells of the developing body and brain. LeVay helped create this field in 1991 with a much-publicized study in Science, where he reported on a difference in the brain structure between gay and straight men. Since then, an entire scientific discipline has sprung up around the quest for a biological explanation of sexual orientation. In this book, LeVay provides a clear explanation of where the science stands today, taking the reader on a whirlwind tour of laboratories that specialize in genetics, endocrinology, neuroscience, cognitive psychology, evolutionary psychology, and family demographics. He describes, for instance, how researchers have manipulated the sex hormone levels of animals during development, causing them to mate preferentially with animals of their own gender. LeVay also reports on the prevalence of homosexual behavior among wild animals, ranging from Graylag geese to the Bonobo chimpanzee. Although many details remain unresolved, the general conclusion is quite clear: A person's sexual orientation arises in large part from biological processes that are already underway before birth. LeVay also makes it clear that these lines of research have a lot of potential because--far from seeking to discover "what went wrong" in the lives of gay people, attempting to develop "cures" for homosexuality, or returning to traditional explanations that center on parent-child relationships, various forms of "training," or early sexual experiences--our modern scientists are increasingly seeing sexual variety as something to be valued, celebrated, and welcomed into society.

In this book, neuroscientist Simon LeVay summarizes a wealth of scientific evidence that points towards a radical new explanation of what makes a person gay, straight or bisexual: Sexual orientation results primarily from an interaction between genes, sex hormones, and the developing brain--biological processes that are already underway in the womb.

Jennifer can’t believe it. Just married and pregnant, she discovers that her husband has been meeting Brad for sex. When confronted, Tom doesn’t deny it, but he insists it’s just “a thing” and he isn’t gay. Elsewhere, John’s wife, Karen, discovers that her husband likes to watch gay porn. John doesn’t understand his wife’s reaction. Why does she care what he watches if he’s not unfaithful? In couple’s therapy, Karen and Jennifer raise the same questions: Does this mean my husband is gay? Can my marriage survive? These and other stories illustrate the difficulties inherent when a wife or girlfriend finds out her man has had or wants to have sexual contact with other men. But many times, the man is not gay or even bisexual. Of course, some men with gay sexual interests are gay men in a process of self-discovery; they are “coming out.” These desires may only reflect a different side of a man’s sexuality or some response to childhood trauma or experiences they have not fully processed. Here Joe Kort and Alexander P. Morgan make the distinction between gay men and “straight men with gay interests” clearer to women who want to know how they can overcome these revelations. The authors explain the many reasons why straight men may be drawn to gay sex; how to tell whether a man is gay, straight, or bisexual; and what the various options are for these couples, who can often go on to have very fulfilling marriages. Is My Husband Gay, Straight or Bi? is intended to help couples understand how male sexuality can express itself in ways that may be difficult to understand. Many marriages have been hurriedly terminated when couples (and their therapists) have lacked the information they needed to understand their current situations. This book provides the clarity, describes the choices, and (in many cases) offers hope for relationships and marriages that have been brushed off as doomed.

A different look at heterosexuality in the twenty-first century A straight white girl can kiss a girl, like it, and still call herself straight—her boyfriend may even encourage her. But can straight white guys experience the same easy sexual fluidity, or would kissing a guy just mean that they are really gay? Not Gay thrusts deep into a world where straight guy-on-guy action is not a myth but a reality: there’s fraternity and military hazing rituals, where new recruits are made to grab each other’s penises and stick fingers up their fellow members’ anuses; online personal ads, where straight men seek other straight men to masturbate with; and, last but not least, the long and clandestine history of straight men frequenting public restrooms for sexual encounters with other men. For Jane Ward, these sexual practices reveal a unique social space where straight white men can—and do—have sex with other straight white men; in fact, she argues, to do so reaffirms rather than challenges their gender and racial identity. Ward illustrates that sex between straight white men allows them to leverage whiteness and masculinity to authenticate their heterosexuality in the context of sex with men. By understanding their same-sex sexual practice as meaningless, accidental, or even necessary, straight white men can perform homosexual contact in heterosexual ways. These sex acts are not slippages into a queer way of being or expressions of a desired but unarticulated gay identity. Instead, Ward argues, they reveal the fluidity and complexity that characterizes all human sexual desire. In the end, Ward’s analysis offers a new way to think about heterosexuality—not as the opposite or absence of homosexuality, but as its own unique mode of engaging in homosexual sex, a mode characterized by pretense, dis-identification and racial and heterosexual privilege. Daring, insightful, and brimming with wit, Not Gay is a fascinating new take on the complexities of heterosexuality in the modern era.

“Heterosexuality,” assumed to denote a universal sexual and cultural norm, has been largely exempt from critical scrutiny. In this boldly original work, Jonathan Ned Katz challenges the common notion that the distinction between heterosexuality and homosexuality has been a timeless one. Building on the history of medical terminology, he reveals that as late as 1923, the term “heterosexuality” referred to a "morbid sexual passion," and that its current usage emerged to legitimate men and women having sex for pleasure. Drawing on the works of Sigmund Freud, James Baldwin, Betty Friedan, and Michel Foucault, The Invention of Heterosexuality considers the effects of heterosexuality’s recently forged primacy on both scientific literature and popular culture. “Lively and provocative.”—Carol Tavris, New York Times Book Review “A valuable primer . . . misses no significant twists in sexual politics.”—Gary Indiana, Village Voice Literary Supplement “One of the most important—if not outright subversive—works to emerge from gay and lesbian studies in years.”—Mark Thompson, The Advocate

What makes people gay, lesbian, bisexual, or heterosexual? And who cares? Written by one of the leading scientists in the research of sexual orientation, Queer Science looks at how scientific discoveries about homosexuality influence society's attitude toward gays and lesbians, beginning with the theories of the German sexologist and gay-rights pioneer Magnus Hirschfeld and culminating with the latest discoveries in brain science, genetics, endocrinology, and cognitive psychology.

Sexual identity has become an idol in both the culture at large and in the Christian subculture. And yet concepts like gay or straight are relatively recent developments in human history. We let ourselves be defined by socially constructed notions of sexual identity and sexual orientation--even though these may not be the only or...
