basic concept
The male is inserted side (passive side): the male unique organ is attached to the pubic symphysis in front of the prostate, and the back is attached to the rectum. Strong stimulation of the anal sphincter and rectum will make the prostate hyperemia, stimulate the ejaculation center, and produce different degrees of pleasure (varies from person to person) ). Haitian science reports show that the intensity of orgasm obtained by men by stimulating the prostate is much higher than that of penile orgasm, which is called prostate pleasure.
Insertion party (active party): The insertion of anal sex can obtain ordinary penis stimulation pleasure. Due to the relationship of the sphincter, the anus will be tighter than the vagina, and the insertion will get stronger pleasure than the vagina.
Studies have shown that people who like anal sex are more likely to obtain a kind of pleasure called "fullness", curiosity and even masochistic tendencies. These feelings are particularly important for the masochistic women who cannot obtain prostate pleasure. Because most women don't like the feeling of holding a bowel movement and pain.
conduct risk
Because there is a sphincter in the anus, its contraction ability is relatively strong, and it cannot be forced to be inserted, otherwise it will easily cause anal fissure. Unsafe anal sex, like other unsafe sex, carries the risk of transmitting STDs, especially HIV. According to advocates of safe sex, condoms should be used throughout any sexual activity, including anal sex, but this is still not considered absolutely safe. Avoiding sexual intercourse with people with known or unknown STDs, taking care of your health, increasing communication with your partner, understanding your physical condition, and discussing activity details can further reduce your risk.
It's worth noting that anal sex, even in the absence of sexually transmitted diseases, carries some health risks. Since the vagina secretes lubricating fluid to assist sexual intercourse, the anus and rectum do not secrete lubricating fluid by themselves. Generally, human lubricants, safe props or condoms can be used to reduce discomfort. However, the epithelial mucosal tissue lining the rectum is highly susceptible to damage during foreign body insertion and friction during sexual intercourse, even with skilled manipulation and the correct and proper use of aids such as lubricants and condoms, with or without Feelings of comfort and even pain can still cause many small wounds that are invisible to the naked eye, which can be detected with test indicators commonly used in forensic or criminal investigations.
Since the normal physiological function of the rectal wall is mainly the passage of feces, the large number of intestinal bacteria does pose a risk of infection. Too frequent anal sex may cause relaxation of the anal sphincter, congestion of the anal mucosa, redness or fissure, and even fecal incontinence and rectal prolapse. It is necessary to avoid serious damage to local organs or serious psychological harm caused by long-term improper anal sex. Forced anal sex can also cause damage to the glans of the penis. However, prior cleaning, avoiding dirty or sharp props, and adequate lubrication can minimize the risk.
Pay attention to the above points when using condoms during anal sex. Use thicker condoms and adequate lubrication to avoid damage to the condoms. Special attention should also be paid to lubricants and condoms. Some oil-based lubricants such as Vaseline are not recommended to be used with rubber condoms, because some oil-based lubricants may have the function of organic solvents to dissolve rubber components.
