When I ordered this book, I didn't notice the number of pages it included. When I received it, I felt daunted, after all this is the largest single book I have ever read even though I'm quite the reader. Once I opened the cover, however, it was difficult for me to put it down. There are a number of illustrations, and some are humorous such as the circumcised penis asking where his hat is! There are quite a few chapters and they are relatively short. Because this is a reference book, it's easy to skip the parts you are not interested in and flip to those you are.

While I believe this would be better for inexperienced people (might make a good gift to a college student?) I believe there is information in this that would be beneficial to anyone. Some of the topics include the history of sex, basic instruction on genitalia, oral, anal, positions, sex toys, birth control, menstruation, STDs, sex during pregnancy, telling your children about sex,a chapter on physical disabilities and sex, plus many more topics. Of course, because these chapters are short, none of these are covered in great length, but each chapter does give a brief overview. There is also an extensive glossary that includes slang terms so if you hear something and are not sure what it means, as an alternative to searching online, you can check the glossary, at least for the more common slang.

One thing I particularly liked was that the chapters are varied in format. For instance, in some chapters there are comments from readers. Some chapters have a recommended resource (although usually not multiple resources) if you want to find out more information on the contents of that chapter. I also liked the fact that when presenting lists of information instead of bullet points, cute illustrations were used such as a cup of coffee, umbrella, and high heeled shoe.
