Fear of sexual intercourse: An abnormal and persistent fear of male-female sexual intercourse. Sufferers of this fear experience undue anxiety because they are preoccupied with failing in some way while having heterosexual intercourse. Among the symptoms of coitophobia are failure to achieve an erection (erectile dysfunction) and failure to achieve orgasm (anorgasmia, or anorgasmy).

The fear of sexual intercourse is termed "coitophobia," a hybrid word derived from the Latin "coitus," which is the past participle of the verb "coire" (to come together), and the Greek "phobos" (fear).
