If there is pain in the vulva and vagina during sex, it is often caused by local inflammation, such as inflammation of the vulva, inflammation of the vagina or local inflammation of a previous lateral wound or local polyp, which may cause pain during intercourse. It is recommended to go to the hospital for examination as soon as possible, and if there is a polyp, give an early removal surgery. If there is an inflammatory condition, actively give anti-inflammatory treatment. It is recommended to pay attention to the hygiene of daily sexual life and menstrual period. If the vagina is painful during sex, it may also be caused by vulvar malnutrition, which leads to atrophy of the vaginal opening and therefore, painful intercourse.
