This book does have some practical application because it presents a thoughtful, though narrow, view of good sex. But it's very elementary and seems to be simply Naura Hayden's view of good sex. The message seems to be, "Get in shape and do it slow." The book is also an advertisement for Naura Hayden to sell her health products. A much more practical and worthwhile book is "How to Make Love All Night (and Drive a Woman Wild)" by Barbara Keesling, Ph.D. Dr. Keesling teaches a direct method of how a man can physically enhance his sexual performance as well as improve his "style" of lovemaking.
