Thankfully, this is not simply yet another a book that simply is from A to Z, discussing each topic in alphabetical order. Instead, it is broken into 27 chapters including not only chapters titled (for example) "Oral Sex", "Growing Up", and "Birth Control"; but also chapters like "Words and Graffiti", "The Liberators", and "In the Sex Store". Each chapter discusses a number of topics. This book is notable for discussing a very wide range of topics most books would not mention. Dense print -- it'd take a long time to read from cover to cover, highly informational.

Lots of illustrations, varying from small line drawings through to full-page color photographs, although the print quality is only average.

The book is good for its information and illustration content, but it doesn't lend itself to bedtime reading or being idly browsed; it's a bit heavy-going. In comparison, a book like "Sexwatching" by Milton Diamond (which I rate 5 stars), although not as diverse and dense in content, has much better visual appeal and can be much more easily enjoyed.
