From the outset we wanted this book to provide broad coverage of male sex work. We sought to include multiple disciplinary perspectives, moving well beyond the public health or sociological focus of much of the earlier literature. We also wanted to capture a sense of the cross-cultural variations in the male sex encounter. Rather than simplifying or condensing our subject matter, we have brought together varied voices that can testify to its complexity and rich diversity. We hope and trust that this book, which presents original research from both young and well-established scholars in the field, brings both breadth and depth to the study of male sex work and gives coherence to the emerging voices of MSWs who are telling their stories. It also provides a broad overview of the literature on MSWs, including studies that have emerged over the last 20 years, and identifies areas for future research.
