At birth, the boy's "penis" was tightly wrapped by the foreskin and closely connected with the penis head, which could not be pulled open by hand. With the growth of age, after puberty, the foreskin should gradually retract, exposing the entire urethral orifice and glans penis.
However, this change will not happen to everyone. For example, in China, 30% of adult males have long foreskin, which means that although the foreskin covers the urethral orifice, they can turn over the glans penis. However, if the foreskin mouth is narrow, or the foreskin is still attached to the penis head so that the foreskin cannot turn up, this is phimosis, which accounts for about 9% of urban men in China.
The foreskin is very useful for primitive people who live in deep mountains and forests. After all, it is terrible to get injured when climbing mountains and drilling grass, but for modern people who no longer hunt and wear pants, its protective effect is meaningless. Now the foreskin has become a big problem-because there are a lot of sebaceous glands inside the foreskin, the secretion will stink and it is close to the urethral orifice, so it is a very troublesome thing to keep this part clean and hygienic.
Children don't understand, it's often difficult to clean without adults' worry, and even adult men's awareness of cleaning is worrying-if you have public toilets on campus when you are in college, you must still have an impression of the crowded women's bathhouses and the empty doors of men's bathhouses.
When this important part is dirty, many problems come. Inflammation, sexual disharmony, penile cancer ... may also transmit human papillomavirus to women, increasing the risk of cervical cancer. Therefore, if phimosis appears, it must be cut; If the foreskin is too long and you don't want to cut it, you should take pains and clean it frequently. Otherwise, you may lose your wife's health if you don't say that you are bitter.
Why not cut:
Of course, after all, it's scary to cut off your own penis, and male compatriots have a low tolerance for diseases. It is estimated that it is quite difficult for everyone to take the initiative to cut this knife. If there is no worry about phimosis and too long foreskin, there is no problem in not cutting it.
When I was a child, circumcision saved me the trouble, but no one knows whether the foreskin will be too long when I grow up. If you get such a knife, something is wrong. But if you wait until you grow up before cutting, the days after the operation will be very painful-you can pay attention to abstinence during the day and avoid stimulating the penis, so you can't make decisions at night. It must be a tragedy to suddenly wake up from a spring dream.
In addition to the above reasons, there is another reason why many male compatriots are determined not to cut-they think that cutting will affect their sexual satisfaction. In fact, there are different opinions on this point. Some people think that masturbation after circumcision is not as good as before, or sexual life is not as good as before; However, statistics also show that the sexual satisfaction of both husband and wife has improved after circumcision. In addition, if a man suffers from premature ejaculation and his foreskin is too long, doctors will generally advise him to do circumcision, because it can reduce the sensitivity of glans penis and delay the ejaculation time.
