Why does sex cause bleeding?

Sexual intercourse is a very important part of a couple's life. During sexual intercourse, the woman may sometimes experience vaginal bleeding. In fact, bleeding during sexual intercourse is a relatively common phenomenon. Many women experience this condition after marriage. Although it is quite common, it is still necessary to find out the cause to avoid making the situation worse in the future. Next, let’s give a simple answer to the question of why bleeding occurs during sex.

1. Cervicitis (erosion). 90% of married women suffer from cervicitis. Cervicitis is divided into three types: mild, moderate and severe according to the degree of cervical erosion. For patients with moderate or severe cervical erosion, the rubbing of the cervix by the glans of the male's penis during sexual intercourse may cause injury and bleeding. Because the amount of bleeding is small, it does not flow out immediately but accumulates in the vagina, and the color of the blood changes from fresh to old. Therefore, when the blood flows out the next day, it is dark red.

2. Cervical polyps. Chronic inflammation may cause cervical polyps due to long-term stimulation of the cervix. Single or multiple small pedunculated granulation tissues grow at the cervical opening, looking like bean buds, and the larger ones are as big as a finger. Polyps are fragile and tender, and will bleed if touched, so bleeding may occur after sexual intercourse. This bleeding is usually bright red.

3. Cervical cancer. Bleeding after sexual intercourse is the earliest symptom. Because there are more small blood vessels and the tissues are more fragile in the cancer lesions, the capillaries will rupture and bleed due to damage after each sexual intercourse. If the cancer grows further, it will bleed more easily.

4. Endometriosis. Some endometriosis grows on the cervix and appears as blue-purple nodules. If this blue-purple ectopic nodule is touched during sexual intercourse, it will cause bleeding. The amount of bleeding is generally small and dark red, and abdominal pain often occurs after intercourse.

5. Pelvic inflammatory disease. Pelvic inflammation can cause pelvic congestion. If the endometrium is congested and edematous, the congested endometrium may bleed after sex, but this chance is rare.

The above is the answer to the question of why bleeding occurs during sex. When women encounter bleeding during sex, they must not panic. It is best to go to the hospital for a gynecological examination and then seek professional diagnosis and consultation from the doctor in order to accurately determine the cause of their own bleeding during sex. I hope the above answers can be helpful to friends who have questions.
