Mutual satisfaction during lovemaking - true fulfillment for both partners - really matters, especially in long-term love relationships. But because of the way our bodies "interface" during straightforward intercourse, women are often left unsatisfied. Throughout history, one-sided sex has been the norm - male contentment and female frustration. Even today, with our improved understanding of sexual anatomy, many couples are still in the same fix. Marshall's carefully researched and superbly written book tells what a few fortunate lovers have discovered - and almost never talk about. "The Great Sex Secret" gives a detailed, straightforward description of three approaches that reliably deliver mutual satisfaction. This book is a perfect conversation-starter for couples who want to find their way to sexual happiness - but are having difficulty talking about the details.
