The presenting complaint in 100 consecutive patients attending the psychosexual session (PSS) attached to the Department of Genitourinary Medicine (GUM) in St Thomas's Hospital was compared with 100 consecutive patients seen at a community PSS attached to a family planning clinic in an outer London district. Patients attending the GUM PSS had a greater fear of infection and more relationship problems, but less erectile failure and loss of libido; there was also a higher proportion of men referred and more patients with no regular partner than in the community PSS. It is concluded that many patients with psychosexual problems sought help from the GUM clinic.
