What should a girl do if she always experiences pain after her first sexual intercourse?

　　The first time generally refers to the first sexual intercourse, which can be improved by performing adequate foreplay, taking appropriate rest, and using medications. Persistent pain after the first sexual intercourse in females may be caused by genital tract injuries, mental tension, rupture of the hymen, vaginitis, cervicitis, etc., with specific analyses as follows:

　　1. Genital tract injury: During the first sexual intercourse, overly aggressive movements, inappropriate positions, or insufficient foreplay can lead to inadequate vaginal lubrication, possibly causing tissue damage, such as perineal lacerations or vaginal mucosal abrasions, resulting in pain. It is recommended to perform gentle movements, ensure adequate foreplay to achieve sufficient vaginal lubrication before engaging in sexual activity.

　　2. Mental tension: Emotions such as nervousness, anxiety, and fear can cause the pelvic floor muscles to remain tense and unable to relax, increasing discomfort and pain. It is recommended to create a relaxed, comfortable, and safe atmosphere. Women can practice deep breathing and relaxation exercises to relax their entire body muscles and alleviate tension.

　　3. Rupture of the hymen: The hymen typically ruptures during first sexual intercourse. The surrounding area contains numerous nerve endings, and the rupture may stimulate these nerves, causing pain along with possible minor bleeding. Pain is usually temporary and tends to subside gradually within several hours after intercourse. It is recommended to rest appropriately, avoid strenuous activity, and maintain external genital hygiene.

　　4. Vaginitis: Failure to maintain hygiene during sexual intercourse may lead to bacterial infection, causing vaginitis. Continuous bacterial infection and inflammatory irritation may cause pain and may also result in increased vaginal discharge. It is recommended to use medications such as metronidazole suppositories or Baofukang suppositories under a doctor's guidance to improve symptoms.

　　5. Cervicitis: Sexual intercourse-related injuries or frequent vaginal douching may cause cervical damage, leading to cervicitis, which can result in increased vaginal discharge, bleeding, and possibly pain. It is recommended to use medications such as azithromycin capsules, Gleditsiae Semen capsules, or minocycline hydrochloride capsules under a doctor's guidance to help alleviate physical discomfort.

　　If the pain persists or worsens, it is recommended to seek timely medical consultation to identify the cause and follow medical advice for appropriate management.
