Female sexual bleeding refers to bleeding in the vagina and external genitalia during or after sexual intercourse in women. Typically, the amount of bleeding is not excessive, and massive hemorrhage is rare. Bleeding can also be caused by local organic lesions of the external genitalia, and timely treatment of these lesions can reduce bleeding. There are other reasons for bleeding during sexual intercourse. Let's take a look at a few:

1. The majority of female sexual bleeding is caused by organic diseases of the reproductive system, with only a minority of cases being caused by rough or inappropriate sexual actions by men.

During the first night of marriage or the first sexual intercourse, bleeding may occur due to the rupture or injury of the hymen. The amount of bleeding is usually small, but in some cases where the hymen is thicker and the male's actions are excessively rough, it can lead to more significant bleeding.

2. In older women, due to atrophy of the gonads and decreased secretion of sex hormones, the vagina becomes atrophied, the vaginal epithelium becomes fragile, the tissue becomes fibrotic and lacks elasticity, and the vaginal secretions decrease, leading to dryness. Rough sexual actions, forced insertion, or inappropriate sexual intercourse can cause vaginal damage, blood vessel rupture, and bleeding.

3. Pregnant women should be particularly careful during the first and last three months of pregnancy, as sexual stimulation of the cervix can cause intense uterine contractions and subsequent bleeding during sexual intercourse. In rare cases, this can even lead to miscarriage or premature delivery.

4. Vaginal dysplasia, narrowness, or deformities can also lead to bleeding during sexual intercourse if the actions are rough, causing tears in the vaginal wall or posterior fornix.

5. Local organic lesions in the female reproductive tract can often lead to bleeding during sexual intercourse. For example, external genital ulcers can cause pain and bleeding during sexual intercourse due to friction. Vaginal inflammation can lead to bleeding due to the large amount of vaginal epithelial shedding and congestion of the vaginal mucosa during sexual intercourse. Growths such as urethral caruncles, which are located near the female urethral orifice and have a fragile texture, can also cause bleeding during sexual intercourse with slight contact.

Cervical erosion, caused by the peeling of the epithelium surrounding the external os of the cervix, exposes the fragile subcutaneous tissue, forming an erosion surface. Bleeding can occur during sexual intercourse due to impact by the penis. Cervical cancer can also lead to contact bleeding during sexual intercourse due to the infiltration of cancer cells and weakening of the tissue. The urethra and vagina are adjacent to each other, and when the urethra is inflamed, it is susceptible to compression and injury during sexual intercourse, leading to bleeding.
