This unique and fascinating book transforms an area of study previously dominated by clinical models to look instead at cross-dressing and sex-changing as a highly variable social process. Giving precedence to the processual and emergent nature of much cross-dressing and sex-shanging phenomena, the book traces the phased femaling career path of the 'male femaler' from 'beginning femaling' through to 'consolidating femaling'. Based upon seventeen years of fieldwork, life history work, qualitative analysis, archival work and contact with several thousand cross-dressers and sex-changers, the book meticulously and systematically develops a theory of 'male femaling' which has major ramifications for both the field of 'transvestism' and 'transsexualism', and for the analysis of sex and gender more generally.
