There are several reasons for women to have vaginal pain during sex: firstly, it is considered that the vaginal wall is lacerated. For women who have sex for the first time, the presence of hymen can cause painful damage to the hymen and vaginal wall. Secondly, as women grow older, the function of ovaries decreases and the secretion of estrogen gradually decreases, resulting in less vulvar and vaginal secretion during sex and therefore a painful feeling during sex. Thirdly, women suffering from vaginal inflammation, such as pelvic inflammatory disease, endometritis and adnexitis, may also cause pain during sex. Fourthly, consider that the male action is too rough during sex, causing damage to the female vagina.
