In the vast majority of women, the hymen is ruptured during the first sexual intercourse. In this case, the rupture of the hymen is usually not particularly painful, but the pain will slowly ease during the course of sexual intercourse, and the amount of blood will usually be only a few milliliters, and will never exceed the amount of menstruation. However, in a few women, the hymen is relatively rich in blood vessels, or the rupture is a little deeper, which can lead to more serious bleeding. In this case it may be necessary to come to the hospital to have the wound treated. In addition, it is not recommended to have sex again in the week after the rupture, and it is important to stop the bleeding and anti-infection treatment.
