THE JOY OF SEX tells the surprising true story behind one of the most successful and influential non-fiction books of the 20th century. Shy British scientist Alex Comfort believes that joyful sexuality could help create a more peaceful society. Inspired by his passionate relationship with Jane and his complex marriage to Ruth, he embarks on an unconventional love triangle that challenges ideas of love, fidelity, and personal freedom. Out of this emotional experiment emerges The Joy of Sex—an illustrated guide that transforms sex from a taboo into everyday conversation. Selling more than 15 million copies worldwide and spending 70 weeks atop The New York Times bestseller list, the book becomes a cultural phenomenon. But while it inspires millions to embrace intimacy with honesty, humour and joy, the man behind the revolution finds himself unable to reconcile his ideals with his own life. A witty, heartfelt and uplifting true story about love, desire, and the price of changing the world.
