Sexual intercourse is a normal physiological need for humans, a way for couples to deepen their relationship, and a necessary process for procreation. However, many women experience discomfort after sexual intercourse. In fact, women should pay attention to these five symptoms that occur after sexual intercourse.

1. Semen allergy
Semen allergy can trigger vaginal itching in women during sexual intercourse. This is because male semen contains various antigens; if a woman has an allergic constitution, she may experience an allergic reaction after intercourse. Mild symptoms include vulvar itching, and redness of the labia and vaginal opening. Severe symptoms can include systemic reactions such as chest tightness, difficulty breathing, and hives-like skin rashes.
2. Bleeding
If it's a woman's first time having sex, or if she has sex during her menstrual period, bleeding is normal. If not, the following possibilities exist:
Injury to the penis; inflammation or sexually transmitted infections; uterine polyps; or a precursor to cervical cell carcinoma. Therefore, any abnormal bleeding after sexual intercourse should prompt a comprehensive medical examination.
3. Headache
Orgasm can trigger fatigue-related migraines because the blood vessels in the brain are fragile, leading to an increase in blood pressure and headaches. These symptoms usually resolve with rest.
4. Pain
While it's common to experience both pleasure and pain during sex, it's important to pay attention to the situation. There are many reasons that can cause pain, such as inflammation, excessive force, vaginal dryness, or allergic reactions. If you experience pain in these situations, you should see a doctor promptly.
