title: Sex and the bowel.
abstract: Patients with gastrointestinal symptoms may not associate their problems with sexual activities or be unwilling to admit to homosexuality. The diagnosis may be delayed or missed and sexual partners are unlikely to be investigated. To complicate matters further the clinical manifestations of some infections may be markedly altered in a patient whose immune system has been compromised by infection with Human Immunodeficiency Virus.
