BACKGROUND: Urethral coitus can occur with vaginal and hymenal anomalies and typically presents with incontinence, dyspareunia, and recurrent urinary infections. Penetration of the urethra occurs unknowingly, and delayed diagnosis permits ongoing urethral coitus and dilation.

CASE: A 23-year-old woman presented to a specialty clinic for a possible vaginal anomaly after failed intrauterine device insertion owing to difficulty locating the cervix. She reported regular menses and satisfying intercourse. Clinical examination revealed a dilated urethra from presumed urethral intercourse and a microperforate hymen with a 1-mm opening.

CONCLUSION: This case highlights the importance of taking a thorough sexual history paired with careful examination of the external genitalia to correctly identify and diagnose vaginal and hymenal anomalies and to prevent long-term complications.

Detailed visual inspection of external genitalia is necessary to accurately diagnose vaginal and hymenal anomalies.
