Love, intimacy, and the tensions of pair bonding

Justin R. Garcia examines romantic relationships through the science of sex, intimacy, and human social life. The book traces a relationship’s life cycle, from initial attraction to long-term commitment, while taking up questions about fidelity, staying or straying, relationship openness, and the influence of digital courtship. Its organizing idea is a tension between social and sexual monogamy: Garcia presents intimacy as a central human need and explores how competing impulses shape romantic choices. The result is a broad account of love and partnership that links individual relationship questions with evolutionary and sociological perspectives.

Good fit for readers who enjoy

  • People interested in research-informed perspectives on love, sex, and intimacy
  • Readers exploring fidelity, relationship structures, or long-term partnership
  • Those curious about how digital life affects dating and courtship

Book overview

In an eye-opening exploration of the most powerful force that drives our species, Kinsey Institute Director Dr. Justin Garcia illuminates the mysteries of how we date, mate and navigate our love lives.

"The best book on modern mating." - David M. Buss, author of The Evolution of Desire.

An Economist pick for "Best Book of 2026 So Far"

Why do we love who we love? Why do we stay in unfulfilling relationships, and stray from rewarding ones? Is it ever a good idea to open a relationship? How has the digital age impacted courtship? And why do some long-time couples crash and burn while others stay madly in love?

In The Intimate Animal, one of the world's leading experts on the science of love and sex answers these questions and more, taking readers on a journey through the lifecycle of a romantic relationship, from the thrill of first attraction to the devotion that lasts decades.

Intimacy is core to the human condition, a key pillar of a loving relationship, and an evolutionary drive. In fact, Dr. Garcia reveals that the need for intimacy -even more than sex drive- is key to our species' survival and flourishing.

But therein lies the challenge. We evolved for social monogamy but not for sexual monogamy, yet these impulses are often at odds. Understanding this tension is the key to aligning our romantic choices with our true desires.

Whether you're seeking that special someone, recovering from heartbreak, or trying to keep the passion alive, The Intimate Animal is the essential, research-backed guide to forging deeper, more intimate connections in these disconnected times.
