There are 5 common causes of lower body pain during sex: 1. Various vaginitis such as bacterial, mycoplasma and chlamydia cause vaginal mucosa congestion and edema, which can cause pain during intercourse. 2. Cervicitis, chronic inflammation causing polyps, cervical hypertrophy and erosion, can cause slight pain during intercourse due to penile stimulation. 3. Herpes vulva, syphilis spirochete infection causing ulcers, can cause pain during sexual contact with secretions flowing to the wound. 4. The pain can be caused by pelvic inflammatory disease and endometriosis, which can cause pain in the lower abdomen and worsen during sexual intercourse. 5. Vaginal dryness is mostly seen in perimenopausal women, where the hormone level decreases and vaginal secretion decreases, and the process of intercourse is painful. There are also some women who have not yet entered the state before sex, and also vaginal dryness causes pain. If you are uncomfortable, you should go to the hospital for examination, treatment and conditioning.
