I have read two books that talk about sex - “She Comes First” and “The Joy of Sex.” I would place this book on a much lower pedestal than "She Comes First." Alex Comfort’s book is one quick read. The content is good, but the format was haphazard. Picture this – The book has four sections called Appetizers, Ingredients, Sauce & Pickles, and Main Courses (not necessarily in that order). Each section contains excerpts about various topics but does not delve into detail. One or two paragraphs at the most and then jump off to another topic. The flow and vibe which one gets by reading these books was missing. Perhaps less segmentation would have helped.
To summarize: At best, a reference book rather than a self-help book. A one-time quick read.
