After a woman's first sexual intercourse, the duration of pain and the amount of bleeding vary from person to person. Some women may experience vulvar pain and bleeding spots after their first sexual intercourse, which can usually subside within a week, and the amount of blood loss will gradually decrease. During sexual intercourse, violence should be avoided to prevent severe tears in the private area. Women usually experience minor vulvar bleeding and pain after their first sexual intercourse, and the duration of pain and bleeding varies for each person. Additionally, not all women experience vaginal bleeding during their first sexual intercourse. For most women, due to mechanical damage during the first sexual intercourse, the hymen may be ruptured, and local mucosal abrasion may occur, resulting in vulvar pain and minor vulvar bleeding caused by the injury. Most of these cases can heal within a week, with bleeding gradually decreasing and pain significantly reducing after 2-3 days. However, if sexual intercourse is violent or the mucosa and tissue of the woman's perineum are tight and inelastic, it can cause severe tears through mechanical damage after sexual intercourse. In such cases, some women have been seen in the emergency room with massive vulvar bleeding and perineal injuries reaching the vaginal vault, which is extremely dangerous. If there is massive vaginal bleeding or persistent severe pain, it is necessary to consult a doctor for examination of severe injuries.
