If the vagina is painful during intercourse, it is not a big problem if it happens once in a while or just once, but if the vaginal fluid is not enough before intercourse, if the vaginal fluid is not enough to enter blindly, or if the male partner is overly forceful during intercourse and stimulates the vaginal mucosa, it may cause pain. As much as possible, you should pay attention to these aspects in your future sex life to avoid persistent pain. However, if vaginal pain occurs frequently during intercourse, it is important to rule out any other diseases, because pain during intercourse can be caused by vaginal inflammation, urinary tract infections, endometriosis, or even low estrogen when there is an endocrine hormone imbalance in the body. This is an abnormal situation and it is important to go to the hospital for examination to avoid the presence of psychological barriers.
