After widespread neglect over many years, the study of human sexuality has recently come to the forefront of many of the most important debates in contemporary society and culture. This book addresses seriously the issue of how to improve the methodological basis of research into non-heterosexual sexualities, exploring the key question of what different methodological and theoretical uses of intersectionality contribute to our understandings of non-heterosexual sexualities. Bringing together research from the UK, USA, Europe and Australasia, this innovative collection rethinks traditional methodologies, creating new epistemologies and applying new approaches, whilst critically examining key issues, including communities, identities, relationships, sexualities, homosexual parenthood, fostering, civil marriage, and politics. As such, it will be of interest to researchers, scholars and students across the social sciences and health professionals.
