Book excerpt: - What libido type are you?: People have different sexual tastes and preferences, which, according to Dr. Sandra Pertot, can be traced to 10 basic libido types--each with a unique set of feelings, desires, and expressions. By learning to recognize them, couples can better understand and work through their sexual conflicts. - A complete guide to a mutually satisfying sexual relationship: Once couples have identified their libido types, Pertot offers useful ways to manage sexual incompatibilities and, in most cases, achieve a mutually satisfying sex life. Her clear advice emphasizes a combination of increased communication, understanding of differences, and building upon previously established aspects of the relationship. - Authoritative information based on more than thirty years of clinical expertise: Pertot was compelled to write this book because in over thirty years of experience counseling couples, she's found that mismatched libidos is one of the most common issues with which couples struggle. She's learned to recognize that most sexual problems are not the result of complicated psychological or relationship issues, but rather have completely sensible causes that can be identified and worked out.
