This book explores the histories and presents of gender dysphoria and euphoria as clinical and theoretical concepts as well as lived experience. It outlines how euphoria emerged as a concept, what its relationship to dysphoria is, and how it shows up in the body, in relationships, and as a framework for liberation. Using the concept of the Möbius Strip as an explanatory model of the interconnectedness of gender, the authors explore how gender as a concept encompasses multiplicity, duality, and non-linearity despite its supposed singularity. Rather than viewing euphoria and dysphoria as two poles of a continuum, this volume introduces the notion that they are in fact a blended experience which oscillates between distinctiveness and relationality. Critically engaging with clinical theory, gender studies, crip theory, spirituality, and political movements, this book is ideal for academics from a variety of fields, including psychology, sociology, gender studies, trans studies, cultural studies, as well as practitioners and clinicians, especially those who work with trans people.
