Chris Ryan is the author, along with his wife Cacilda Jetha, of the New York Times bestseller “Sex At Dawn: How We Mate, Why We Stray, and What It Means for Modern Relationships,” which advice columnist Dan Savage described as "the single most important book about human sexuality since Alfred Kinsey unleashed Sexual Behavior in the Human Male on the American public in 1948."

In this wide-ranging interview with The Young Turks’ Ana Kasparian, Ryan discusses why sexual monogamy among humans is a very recent invention, the critical difference between intimacy and sex, why polyamorous relationships are often much healthier - with better communication and less jealousy - than traditional pair bonds, the primitive roots of the cuckolding fetish, and why it can be perfectly OK to say, “go ahead, fuck the nanny.”
