This is t a textbook r an encyclopedia; rather, it is a collection of papers representing a variety of points of view on contemporary is- sues, controversies, and questions about female sexual development. The editor has a point of view, t a point of view as to which of the various authors' positions presented in this book is correct, or even the most useful, but a point of view about the format of such a book; namely, that the definitive answers, and the experts who will provide them, are t yet identified. Therefore, many voices should be heard from different areas of expertise, training, experience, and back- ground. Inevitably there are contradictions and disagreements. There should be. Several authors who were asked to provide short discus- sions for papers found themselves unable to answer in less than an ad- ditional paper. The editor welcomed this response. This is an area full of ancient myths, new discoveries, and alternate perspectives. It is hoped that the book reflects these ambiguities and controversies and that it will stimulate as many questions as it provides answers. You will find represented in this volume, and its forthcoming companion volume on women's sexual experience, authors t gener- ally found together between the covers. When useful and where pos- sible, a discussion or an addendum to a paper has been included by an author who approaches the subject from a different base of infor- mation or experience.
