There will be blood when two people have sex

Having sex is a very good way to increase the relationship and pleasure between men and women. During sex, it mainly relies on contact between the lower bodies of men and women. Because the private parts of both men and women are very sensitive areas, if they are rubbed for a long time, it will bring great pleasure to people. Some people have found that when two people have sex, the woman will bleed. What is going on?

Bleeding during intercourse is a type of contact bleeding. Another type of contact bleeding is bleeding caused by touch during a doctor's examination.

There are many gynecological diseases that cause bleeding during intercourse, the most common ones include cervical polyps, cervical erosion, submucous uterine fibroids, post-IUD insertion, senile vaginitis, cervical cancer, vaginal cancer, etc. Cervical erosion and cervical polyps are both manifestations of chronic cervicitis. Cervical polyps are caused by the stimulation of chronic cervical inflammation. They are formed by local hyperplasia of the cervical canal mucosa, which gradually protrudes outward. The surface is covered with a layer of columnar epithelium and has abundant microvessels, which are easy to bleed when touched. Cervical erosion is also caused by long-term inflammatory stimulation, which causes the squamous epithelium on the surface of the cervix to fall off, and the peeling surface is gradually covered by columnar epithelium derived from the proliferation of the cervical canal. The columnar epithelium is very thin, and underneath it are blood vessels and stroma, so it is easy to bleed during sexual intercourse.

Women with submucosal uterine fibroids, especially those protruding from the cervix, may experience bleeding during sexual intercourse because the mucosal surface is prone to ulcers and infections. Women who use contraceptive rings may sometimes experience bleeding during sexual intercourse. This is because the intrauterine ring is a foreign body in the uterine cavity. Its mechanical pressure can cause local damage, necrosis and ulcers of the endometrium, and there is a possibility of bleeding. In this case, the stimulation of sexual intercourse can cause bleeding. Early symptoms of cervical cancer may also include bleeding during intercourse, which is why we should pay attention to bleeding during intercourse. The cervix of patients with early cervical cancer may not show obvious changes, or cancer and cervical erosion may exist at the same time. Cervical cancer bleeds easily when touched, mostly because the cervical cancer tissue invades the blood vessels in the interstitium. Postmenopausal women are prone to senile vaginitis due to the lack of estrogen. At this time, the vaginal mucosa becomes thinner and may be damaged during intercourse, causing bleeding. In addition, the initial manifestation of primary vaginal cancer is only bleeding after sexual intercourse, and patients with chronic pelvic inflammatory disease sometimes also have bleeding during sexual intercourse. Both situations are relatively rare. As for women who experience bleeding during intercourse shortly after giving birth, it may be damage to the vaginal wall and they should seek medical attention promptly.
