For much of the 20th and 21st centuries, women’s sexuality was an uncharted territory in science, studied far less frequently - and far less seriously - than its male counterpart. That is, until Emily Nagoski’s Come As You Are, which used groundbreaking science and research to prove that the most important factor in creating and sustaining a sex life filled with confidence and joy is not what the parts are or how they’re organized but how you feel about them.

Since Darwin's day, we've been told that sexual monogamy comes naturally to our species. 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....

Challenging accepted theories about what makes for terrific sex, The Erotic Mind is a breakthrough exploration of the least understood dimensions of human sexuality - the psychology of desire, arousal, and fulfillment. Sex therapist Dr. Jack Morin offers a new perspective that celebrates the joys of Eros without denying its risks. Based on an in-depth analysis of over 1,000 provocative stories of peak sexual experiences, The Erotic Mind offers clear, accessible guidance on how anyone can utilize their own peak encounters and fantasies as powerful tools of self-discovery.

Robert Sapolsky’s Behave, his now classic account of why humans do good and why they do bad, pointed toward an unsettling conclusion: We may not grasp the precise marriage of nature and nurture that creates the physics and chemistry at the base of human behavior, but that doesn’t mean it doesn’t exist. Now, in Determined, Sapolsky takes his argument all the way, mounting a brilliant (and in his inimitable way, delightful) full-frontal assault on the pleasant fantasy that there is some separate self telling our biology what to do.

Burnout. Many women in America have experienced it. What’s expected of women and what it’s really like to be a woman in today’s world are two very different things - and women exhaust themselves trying to close the gap between them. Sisters Emily Nagoski, PhD, and Amelia Nagoski, DMA, are here to help end the cycle of feeling overwhelmed and exhausted. Instead of asking us to ignore the very real obstacles and societal pressures that stand between women and well-being, they explain with compassion and optimism what we’re up against - and teach us how to fight back.

An affair: It can rob a couple of their relationship, their happiness, their very identity. And yet this extremely common human experience is so poorly understood. Adultery has existed since marriage was invented, and so, too, the prohibition against it - in fact it has a tenacity that marriage can only envy. Iconic couples' therapist and best-selling author of Mating in Captivity Esther Perel returns with a groundbreaking and provocative look at infidelity, arguing for a more nuanced and less judgmental conversation about our transgressions.

Long before the term cuckold was a common word thrown around in the media, Dr. Ley explored the history and science of cuckolding. This groundbreaking work explores why and how some men not only allow, but encourage, their wives to pursue sexual relationships with other men.

Open Monogamy is Dr. Nelson's guidebook for couples who wish to explore new directions in their relationships - to bring in excitement, variety, and fresh experiences without sacrificing trust, security, and respect. In this practical, skill-based book, she helps you find your place on the "monogamy continuum"; have honest conversations about attraction and desire; remove shame and suspicion from an open relationship; and create agreements - traditional or otherwise - that are fulfilling, exhilarating, and built for enduring love.

The study of sexual physiology has been a paying career or a diverting sideline for scientists as far-ranging as Leonardo da Vinci and James Watson. The research has taken place behind the closed doors of laboratories, brothels, MRI centers, pig farms, sex-toy R&D labs, and Alfred Kinsey's attic.

Mary Roach, "The funniest science writer in the country", devoted the past two years to stepping behind those doors. In Bonk, Roach shows us how and why sexual arousal and orgasm can be so hard to achieve and what science is doing to slowly make the bedroom a more satisfying place.

Based on the popular research project Whores of Yore, and written with her distinctive humor and wit, A Curious History of Sex draws upon Dr. Kate Lister's extensive knowledge of sex history. From medieval impotence tests to 20th-century testicle thefts, from the erotic frescoes of Pompeii, to modern-day sex-doll brothels, Kate unashamedly roots around in the pants of history, debunking myths, challenging stereotypes, and generally getting her hands dirty.

Magnificent Sex is based on the largest, in-depth interview study ever conducted with people who are having extraordinary sex. It gathers the nuggets for remarkable sex from the "experts", distilling them into an attainable blueprint for ordinary lovers who want to make erotic intimacy grow over the course of a lifetime.

With In Each Other's Care, Stan Tatkin shares a hands-on repair manual that will help you discover how arguments get triggered, why they keep happening, and what you can do to get better at communicating what you want without the drama.

From the number-one New York Times best-selling author of Primates of Park Avenue, a bold, timely reconsideration of female infidelity that will upend everything you thought you knew about women and sex. In Untrue, feminist author and cultural critic Wednesday Martin takes us on a bold, fascinating journey to reveal the unexpected evolutionary legacy and social realities that drive female faithlessness, while laying bare our motivations to contain women who step out.

A full one-fifth of the United States has engaged in consensual non-monogamy (CNM) at some point in their lives, and 29 percent of adults under 30 today consider open relationships to be morally acceptable—yet there are few resources to turn to when it comes to navigating this more non-traditional and explorative territory.
