This book provides a criminological analysis of the evolving BDSM scene in Central Europe, with an emphasis on selected post-communist countries. It explores how the region’s communist past delayed the development of BDSM communities and public discourse compared to Western Europe. Examining themes like mediatization, commodification, and globalization, the book traces the shift of sadomasochism from a criminalized and medicalized diagnosis to an accepted, consensual sexual practice. Focusing on issues of law, consent, and societal norms, this book investigates the growing online BDSM communities and the rising demand for paid services, including the phenomenon of financial domination. By analyzing professional BDSM practices, the book addresses how criminal law intersects with consensual sadomasochism, highlighting the complexities of distinguishing between consensual and non-consensual acts in both legal and social contexts. Using quantitative research, the book also presents data on societal attitudes toward BDSM in the Czech Republic, shedding light on the growing tolerance of consensual BDSM practices, even among university students. These findings are critical in understanding how legal frameworks and public perceptions influence the stigmatization or acceptance of BDSM within criminology. As the first comprehensive criminological study of BDSM in Central Europe, this book offers a unique perspective on the intersection of sexual practices, law, and society.
