Practice makes pleasure. because this book is based on a three thousand- year tradition of actual sexual experience, the authors are well aware of the effort that is involved—pleasurable as it may be—in changing your sex life. Learning sexual secrets is one thing, but using them is quite another. The techniques in this book have been tested and refined by countless lovers over thousands of years in the laboratory of real life. We have tried to present them in as clear and simple a way as possible, but the only way to benefit from them is to really use them.
