“Sex is not about reproduction. At all.” Today on BOLD, LeGrande Green interviews sex researcher Christopher Ryan about the provocative history of marriage and sexual boundaries. “If you look at it from a historical sense,” he says, “monogamy is propaganda, not science. I often compare it with vegetarianism…it’s a choice.”

A self-proclaimed “shame exorcist,” Chris is the co-author of Sex at Dawn: How We Mate, Why We Stray, and What It Means for Modern Relationships. Dan Savage calls It “the single most important book about human sexuality since Alfred Kinsey unleashed Sexual Behavior in the Human Male in 1948.” LeGrande and Chris discuss:

• why long-term fidelity can be so difficult
• why many middle-aged men risk everything for an affair
• why homosexuality persists in the face of evolutionary logic
• 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 offers a revolutionary new understanding of why we live and love as we do. Chris’ website is www.chrisryanphd.com. Join the conversation at www.getboldtoday.com.
