Normally, female superior position will not cause cervical bleeding. However, if a woman suffers from cervicitis, the tissue on the surface of the cervix is in a state of congestion and edema, and if the female upper position is inserted deeply and touches the location of the lesion, it will easily cause bleeding symptoms. If a woman has cervical polyps, it can also lead to contact bleeding. In addition, when a woman has a submucosal fibroid protruding from the cervical opening, it can also cause bleeding and is often mistaken for cervical bleeding. In fact, these are usually not related to sexual position. Therefore, if post-coital bleeding occurs repeatedly and many times, and is not related to sexual positions, you must go to the hospital promptly for medical examination to see if it is due to cervical lesions. In addition, when menstruation has just ended, as the vagina and endometrium have just been repaired, bleeding can also be caused after sexual intercourse, which is a normal situation and usually has nothing to do with the female superior position either, and if it is not accompanied by other abnormal symptoms, it usually does not require special treatment.
