The penis is the male sexual organ whose main functions are urination, ejaculation and mating. Having a normal penis is not only related to men’s physical health, but also plays an important role in maintaining men’s self-confidence and harmony between husband and wife. So what is considered a normal penis? About circumcision and prepuce The male foreskin is the skin of the penis folded into a double layer at the head of the penis. In infancy, the foreskin is long and wraps around the penis so that the glans and urethral opening cannot be revealed. As men develop, the foreskin recedes and the glans and urethral orifice are gradually exposed. However, in some adult men, the foreskin still completely covers the glans and urethral orifice of the penis. Among them, the foreskin can still be turned up to reveal the glans and urethral opening is called prepuce; the foreskin can not be turned up is called prepuce. Patients with prepuce need early surgery to avoid affecting growth and development. There are a few patients who are overcircumcised, but not all of them need surgery. Generally speaking, for those patients who have adhesions of the foreskin, narrow foreskin opening that is difficult to turn up, repeated inflammation of the foreskin and glans, painful intercourse, and short ties. Early surgical treatment is recommended. The rest just need to pay attention to local hygiene and wash the glans every day. About short penis Many men lack a correct understanding of penis size due to misleading bad information and mistakenly believe that their penis is short, which seriously affects their self-confidence. In fact, a weak penis greater than 3 cm and an erection greater than 8 cm is a normal size, and it can complete a normal sex life, not to mention not affecting fertility. Moreover, the size of the male penis and the sexual pleasure of the female partner is not directly proportional, but is related to the communication, cooperation and skills of both parties. For patients whose penis is smaller than the normal range, hormonal tests are needed to clarify the cause of penile shortening. For patients with occult penis whose penis development is normal but the penile body is buried in subcutaneous fat, surgical correction is needed. There is a controversy in the current medical community regarding the understanding of penile lengthening. Generally speaking, penile lengthening can lengthen the penis by 1 to 3 cm, but many patients respond that there is a decrease in erectile hardness after surgery, so surgical lengthening of the normal penis is generally not advocated. Penis enlargement is not recommended because of the many complications. About masturbation Masturbation is also known as masturbation. Chinese medicine and some religions believe that masturbation is shameful and can easily lead to kidney deficiency and reduced sexual function. But in fact, scientific surveys have found that more than 90 percent of men have masturbated. In general, moderate masturbation has no effect on health and does not cause impotence and early. It is generally believed that masturbation should not exceed three times a week, otherwise it will cause fatiguing erectile dysfunction. After masturbation, pay attention to cleaning the penis to avoid causing glansitis of the foreskin. The most important thing to remember is that the penis is not able to achieve and (or) maintain an erection sufficient for a satisfactory sex life, and ED is divided into psychological ED and organic ED. The majority of young men belong to psychological ED, which is caused by psychological factors such as lack of sexual experience, stress, depression, anxiety and couple relationship. Generally speaking, these patients need to strengthen the sexual experience learning and communication and cooperation between the two sides, do not use aphrodisiac drugs indiscriminately. For patients with organic ED, it is generally recommended to check sex hormones, penile vascular ultrasound, nocturnal penile erection test and other tests to make a clear diagnosis and reasonable treatment. Premature ejaculation is considered normal when the penis enters the vagina for more than 2 minutes and thrusts for more than 20 times during sexual intercourse, and vice versa. For patients with combined erectile dysfunction and premature ejaculation, erectile dysfunction must be treated before premature ejaculation can be treated. Many men mistakenly judge premature ejaculation by the time they masturbate, which is wrong. There are many psychological factors that cause premature ejaculation, such as lack of experience, fear of failure in sexual intercourse, emotional tension, lack of cooperation and communication between husband and wife, etc., which can cause premature ejaculation. For these patients, especially young patients, they can strengthen their sexual life skills and couple cooperation to enhance their control and prolong their sexual life. Premature ejaculation treatment drugs have more or less side effects, should be applied under the guidance of a physician, do not use drugs indiscriminately. Proper understanding of the male penis and attention to male penis hygiene and health are abilities that men need to master throughout their lives. When there is a penis health problem, it is recommended to use the platform “My Doctor” to consult a specialist in a timely manner, do not believe in bad information and use drugs indiscriminately.
