Bleeding during intercourse may result from overly vigorous movements that irritate and rupture blood vessels in the vaginal wall. It could also be caused by conditions such as cervical hypertrophy or cervical erosion, which leave the cervix in a congested state and prone to contact bleeding when stimulated. Additionally, contact bleeding can occur in patients with diseases such as vaginitis or cervical polyps.
