Woman's anal sex

Yellow chrysanthemum refers to the anus, and it is named because the wrinkles of the anus resemble a yellow chrysanthemum. Anal sex refers to the use of a strip of object thicker than the anus to insert into the anus, in order to achieve a posture close to that of mating. The word "explosive" is used to modify the adjective situation because its thickness may exceed the relaxation level of the anus. So, what harm does anal rape do to a woman?

1. Very susceptible to sexually transmitted diseases

The risks of anal sex are many times higher than vaginal sex. The biggest problem is that it is very easy to get infected. The main reason is that the duodenum is very easy to absorb fluid, and anal sex is very easy to cause wounds to the anus. If one party has a sexually transmitted disease, such as HIV, amoeba, mycoplasma, etc., it is easy to be infected through unprotected anal sex. Even if a condom is worn, it is easy for it to tear or fall off during anal sex, causing danger. Anal sex can also cause infections such as syphilis, genital warts, and chancroid.

Anal sex is very likely to cause infection with human papillomavirus (HPV), which has been linked to anal cancer, although anal sex does not directly cause cancer. People who repeatedly engage in anal sex have a seven-fold increased risk of anal cancer.

2. Anal structural damage

The vagina is composed of epithelial cell tissue, while the anus is much more sensitive in comparison. The forced insertion of the male genitals during anal intercourse can easily cause damage to the duodenal mucosa at the anus. The anus has two types of epithelial tissues in terms of anatomical characteristics: below the dentate line where the anal skin and the duodenal mucosa meet is a double-layer squamous epithelium, which has good wear resistance and flexibility, and this part is controlled by the somatic nerves, and the sensory nerves are relatively sensitive; above the dentate line is a single columnar epithelium, which is easily damaged by friction, and this part is controlled by the visceral nerves, and the sensory nerves are not sensitive, and may not be aware of injuries.

Anorectal ulcers are very common among lesbians. Ulcer lesions mostly occur on the posterior wall of the duodenum 5 to 7 cm away from the anus. The ulcers are deep and often bleed. The ulcers caused by damage to the duodenal mucosa are difficult to heal and sometimes become hard, which can easily be mistaken for colorectal cancer. The main treatment method is to stop anal intercourse. If there is a combined infection, antibiotic treatment should also be carried out.

The anus and duodenal tissues cannot metabolize fluids like the vagina and have a lubricating effect. Therefore, anal sex can easily tear the external anal sphincter if lubrication is not used. Some people take drugs such as alcohol to relieve the sensitivity of the anus, which makes it more likely to cause damage.

Anal sex can aggravate hemorrhoids. Hemorrhoids are caused by hypertrophy and hematoma of the fibrous connective tissue at the anus. Severe patients may experience internal bleeding during anal sex.

Although anal sex does not necessarily cause intestinal and fecal incontinence, it may occur in a very small number of people after repeated damage to the anus.

3. Excrement pollution leads to many diseases

There is excrement in the anus and duodenum, which contains a lot of infectious microorganisms. Even if a cleansing enema is performed before anal sex, it is usually not cleaned out.

In addition to causing infection in the wounds caused by anal sex, these microorganisms can also cause "intestinal tract syndrome": after anal sex, the fingers and genitals are contaminated with feces, causing the spread of bacteria, and contaminated food and tableware allow the bacteria to enter the human digestive system. After a critical period of 6 to 72 hours, the patient develops serious salmonella and other infections, and may suddenly experience abdominal pain, diarrhea, nausea, vomiting and fever. Some people also have headaches, muscle pain, back pain. If not treated promptly and completely, it can easily become chronic. He recommended that patients should discontinue the habit of anal intercourse after the onset of this condition.

If you do not clean up after anal sex and have vaginal sex soon after, the bacteria from the anus can be brought into the vagina and cause infection.

4. Cause severe pain

Some people have seen from the "Island action movies" downloaded for free on the Internet that anal sex is often a "reserved program" and does not seem to cause any discomfort to the defendant. However, this is actually a lie. In reality, if many people are not careful when performing this kind of behavior, both parties may feel pain, and sometimes the pain is very severe. A survey found that 12% of gay men find anal sex too painful to engage in. The key cause of pain is that the external anal sphincter is covered with sensory nerve endings.

Research shows that anal pain is related to both physiological and psychological barriers, including insufficient lubrication, anxiety and restlessness, among which psychological barriers are the main ones. Improving communication between the two parties, improving lubrication measures, and adequately relieving stress may relieve the pain.
