Of interest to psychotherapists and counsellors of all kinds, this text describes key issues and controversies in human sexuality as they present in therapy practice. The author uses the biopsychosocial approach to human behavior to analyze sexual behavior, object choice, transgendered experience, sexual problems, transgressive sex and sex therapy. Issues of sexuality in the consulting room, including transference and countertransference, are discussed and, throughout, therapeutic approaches to sexual problems are presented. The human capacity for inventive imagining is presented as an important force for beneficial change and, in relation to sexuality, discussed in terms of the "erotic imagination."
