Sexuality has always been conceptualised as a potential problem. The regulation of sexuality and the distinction between normality (healthy sexuality) and abnormality (sexual problem) have a long history, in which psychologists have been deeply involved. Yet all attempts to develop a single psychology of sexual problems are fraught with difficulties. There has also been much criticism of the idea of a psychology of sexuality, and of dysfunction, particularly from authorities in psychoanalysis and feminism. In Psychological Perspectives on Sexual Problems, originally published in 1993, these controversies and debates are critically examined, while also addressing the need for individuals with difficulties associated with sexuality to receive help. Psychological theories associated with sexuality and sexual problems are examined, along with examples of positive and empowering practice with groups of individuals whose sexuality is often marginalised by psychologists. These include people with learning difficulties or physical disabilities, sex offenders, injecting drug users, gay men with AIDS and women with eating disorders. Psychological Perspectives on Sexual Problems was the first book to integrate critical theory and current clinical practice. It offered a radical new approach to the psychology of sexuality at the time. Today it can be read in its historical context.
