SummaryThe widely known behavioural method of treating sexual problems developed from the work of Masters and Johnson and others applies to couples who complain overtly of specific measurable dysfunctions in sexual performance. It does not apply comfortably to those who bring their sexual difficulties to the family planning or gynaecological clinic. These usually complain individually, often in the guise of other presenting symptoms, and are in difficulty with their own sexual confidence rather than with relationship problems or technical ignorance.
