Sex Crimes. Psychopathology of Crime offers a fascinating historical tour of the complex boundaries that have defined sexual behaviors throughout history. From social license to the boundaries set by law, this book explores the evolution of legislative frameworks and their impact on respect for individuals, regardless of gender, in diverse cultures and civilizations. Through an in-depth, multidisciplinary analysis, the book invites the reader to reflect on the notion of consent in sexual relations and its interpretation in different legal contexts. From clinical data to legal and social analysis, the book culminates in the current situation in Spain, where recent laws have generated a movement worthy of study. Blanca Navarro and Alicia Romero, forensic experts and therapists specialized in sexual crimes, contribute their vast experience in cases of sexual crime complaints, both in the evaluation of victims and aggressors, some of them with a high media profile. An essential work that sheds light on a crucial issue in contemporary society, analyzing both its historical context and its relevance in the legal and social landscape.
