The Penis Enlargement Bible is a good book. The only problem is that it spends most of the time talking about several things. Even the tips and techniques given by the author are nothing new. I have tried the techniques, and the results were only a partial improvement in the size and girth. Some of my friends also tried the methods mentioned in the book, and they also reported seeing no noticeable change.
Be that may, some of the tips are good enough, and pages dedicated to ED is the saving grace for this book.
