Excessive force during intercourse may lead to vaginal bleeding. If the intercourse is not gentle and the force is too strong, it may cause damage to the mucous membrane of the vaginal wall and tearing. In this case, the vaginal bleeding will be heavy and fresh, and the woman will need to go to the hospital as soon as possible to have the mucous membrane of the vaginal wall surgically removed and stitched up. Vaginal bleeding is not necessarily caused by excessive force during intercourse, but may also be caused by cervical lesions such as precancerous cervical lesions, cervical cancer, or cervical polyps; in addition, it can also be caused by inflammatory diseases such as endometrial inflammation, cervical inflammation, and vaginal inflammation, which can also cause vaginal bleeding after intercourse.
