Is anal penetration harmful to boys?

Male homosexuals often have anal sex. If you are not careful, this type of anal sex can easily lead to some diseases. This is also an important cause of AIDS. Anal sex can easily cause damage to the rectal mucosa. Sometimes the anus is damaged to the point where it is difficult to repair. Let's find out if it is harmful for boys to insert anus. Let's take a look.

Anal sex is generally not recommended. It is easy to get intestinal diseases, and if the man does not use a condom, it will cause some reproductive diseases in the man. And if the woman bleeds, the bacteria will directly infect the man's glans. So it is not recommended to have sex in this way. Pay more attention to local hygiene in the near future, and wash frequently with lotion.

Anal intercourse can easily cause damage to the rectal mucosa. The rectum is a weakly alkaline environment, which is suitable for the survival of HIV. The HIV contained in semen injected into the rectum can enter the blood through the damaged mucosa and spread throughout the body with the blood flow. Moreover, this method of infection does not necessarily require damage to the mucosa.

According to research, there are many Langerhans cells on the surface of the rectal mucosa. HIV can directly enter these cells and multiply in large numbers inside them. The virus is then released into the blood and spreads throughout the body through the blood flow, which increases the risk of infection through anal sex.

The vagina is made of epithelial tissue, while the anus is much more fragile. Forced insertion of the penis during anal sex can easily damage the anal rectal mucosa. Liu Shaojie introduced that the anus has two types of epithelial tissues in terms of anatomical characteristics: below the dentate line where the anal canal skin and rectal mucosa meet, there is a multi-layer squamous epithelium, which has good wear resistance and stretchability of the skin. This part is innervated by the somatic nerves and is more sensitive to pain; above the dentate line, there is a single-layer columnar epithelium, which is easily damaged by friction. This part is innervated by the visceral nerves and is not sensitive to pain, and you may not know it even after being injured.

Anal sex-related rectal ulcers are very common among homosexuals. Ulcers often occur on the posterior wall of the rectum 5 to 7 cm away from the anus. Ulcers are relatively deep and often cause bleeding. Ulcers formed after damage to the rectal mucosa are delayed in healing and sometimes become hard, which can be easily mistaken for rectal cancer. The main treatment method is to stop anal sex. If there is a concurrent infection, antibacterial drug treatment is also required.

Anal sex can aggravate the symptoms of hemorrhoids. Hemorrhoids are caused by hypertrophy and congestion of the fibrous connective tissue of the anus. Severe patients may bleed heavily during anal sex. Anal sex can also easily lead to intestinal loss of control and fecal incontinence, which may occur in a small number of people after repeated anal injuries.
