Book excerpt: This book tells the true story of a retired nuclear physicist who had three marriages and one living-together relationship before finally getting it right with his fourth marriage. It deals primarily with his sexual experiences that start with early childhood and continue to the present time. He concentrated on sex because it plays a key role for most people in all phases of life. One only has to look at the news media to see how big a factor (often dysfunctional) this is for many. Most of his early relationship failures can be attributed to being naive. For each phase of his life, he has compiled a set of lessons that could be of value to others experiencing similar problems. Throughout the book, the author uses words and describes graphic sexual acts that may offend some people. This was done largely to reflect the language and actions that are appropriate for the situation described. Finally, he felt that a book of this type would be quite different coming from the point of view of a person with a scientific background. It is hoped that readers will agree with this assumption. Only time will tell!
