If you have pain down there after sex, you should first consider whether it is due to external stimulation, if the lovemaking process is more violent, consider the external factor. In addition to external factors, it is also possible that the pain is caused by inflammatory factors. For example, pelvic inflammatory disease and vaginitis can cause pain, sometimes accompanied by abnormal and increased leucorrhea. If there is no organic lesion, the pain may be caused by insufficient vaginal lubrication, vaginal discharge, and friction through sexual intercourse may rub the vaginal mucosa and cause pain. If it is caused by a disease, it needs to be examined, diagnosed and treated in a hospital. If it is caused by external force, you need to be gentle during sex. If it is due to lack of vaginal lubrication, it is advisable to add more foreplay or use lubricant to make it fully lubricated before making love. Before and after sex, you should clean your vulva, do a good job of hygiene, wash your underwear regularly, and preferably wear loose and breathable cotton underwear. If it is caused by inflammation, you need to pay attention not to eat spicy and stimulating food, a light diet, and forbid sex during the medication.
