Size Matters is one of the most informative sex and health books I have read in a long time. It answers tons of questions women may have about their guys. Each chapter follows a question and answer layout and contains tons of facts and a few diagrams throughout to aid the answers. The only downside is the intended audience. This reads as if it is meant strictly for women in a heterosexual relationship to read.

The authors introduce this book as an encyclopedia of sorts written for women. This is surprising to me because much of this information is common knowledge to women and would be better received by a male audience. Also, the type of humor used may be more entertaining to a male's. Overal, I did not enjoy this book and would not suggest it to anyone. This is the only product I have ever given less than three stars, if I could give it zero, I would.

"Size Matters" is an amazingly educational and laid-back book. It contains so much information about the male anatomy that I feel like it honestly should be required reading for all adults. It's a great book.

This book is a good, contemporary choice, for reading about issues of sexual health and performance. It addresses the questions you need to know, such as transmission of sexual diseases, and the questions you want to know, such as what really is the average penis size. You can get answers about a lot of the questions that you really wouldn't know where to get a true answer from someone with factual medical knowledge.
