Sensible, well-based advice on avoiding boredom, improving technique, and just plain finding time once marriage has set in. O'Connor (director of New York's St. Luke's-Roosevelt Hospital's Sexual Therapy Program) has a wealth of clinical experience and case histories to draw on, and her confortable, chatty style puts her points across well. She dispenses with the common excuses in ""How We Turn Ourselves Off"": among the big problems are mood, family roles (how to switch from Mommy and Daddy to Lovers), interruptions by children, and fear of intimacy. In ""Resisting Temptation,"" O'Connor makes it absolutely clear that infidelity in a marriage means that one partner has given up on the relationship--affairs, simply, are out if one wishes to have a solid relationship (a lesson learned clearly from the Open Marriage days). Then, O'Connor turns her attention to ""How to Turn Ourselves On""--technical and emotional advice, with another big push for the art of scheduling time to be alone together and sticking to it--the ""date"" should be as important as a business meeting. No hype or fads here; just solid advice on how to keep sex an important--and fun--part of long-term relationships.
