This book responds to the need to investigate the complex links between sex and leisure and their implications for research and practice. Understanding sex as leisure aligns with sex-positive culture that focuses on affirming pleasure in the contemporary sexual discourse and advocating for sexual diversity, freedom, empowerment, and fulfilling sex lives. The focus of this book is on analyzing the complexity of sex as leisure in various socio-cultural and geographical contexts, with particular reference to vulnerable populations and pressing sexual issues, including sexual pleasure and expression, biomedicalization of sexuality, and social justice and sexuality. Specific chapters offer diverse international coverage and address the links between a positive sexuality framework and leisure research. The chapters cover sexual play and sex toys based on consumer experience perspectives; using the leisure lens to analyze sex and pornography addiction; quadriplegic sexuality and leisure; rejection and resilience on a gay cruise; relational dynamics of aging, exploitation, and deceit in sex tourism; sexual harassment of solo female travelers; and the complexity of consent in the sexualized leisure space of a pornography expo. This book will be of great value to those interested in transdisciplinary scholarship as it critically broadens the bio-psycho-socio-cultural perspective of sex as leisure. The chapters in this book were originally published as a special issue of the journal, Leisure Sciences.
