Men always worry about this problem, which must be uncomfortable.

Many Chinese scholars have conducted thousands of surveys on the standard of normal male penis size, but there are large differences in the measurement results of different scholars. In addition to being affected by factors such as region and ethnicity, this is mainly because the length of the penis of the same person in a flaccid state is not constant, and the measurement methods are not exactly the same. What is certain is that it is not appropriate to judge whether the penis is normal based on its length. As long as a man's penis can enter a woman's vagina when erect and can complete sexual intercourse, it is normal.

The size of the penis changes unpredictably when it is in a flaccid state. For example, when you are nervous, tired, or cold, the penis will be relatively shorter. However, for the same person, the size of a fully developed penis remains constant after it is fully erected. Therefore, penis size is usually measured by its erect length. However, because the person being examined is nervous or not adapted to the examination environment, he or she is often unable to achieve a complete erection during the examination. Therefore, in medicine, the stretched length of the penis is often used to represent the erection length. The so-called penis pulling length refers to pinching the coronal sulcus of the glans penis with the thumb and index finger to lift the penis flat, pulling the penis to fully stretch it, and then using a hard ruler to press slightly against the pubic symphysis at the base of the penis to measure the length to the external urethral opening of the glans penis.

The size of the penis varies greatly between different people when it is flaccid, but this difference decreases after it is erect. In other words, whether the penis is larger or smaller when flaccid, once it is erect, the size is always the same. That is, a smaller penis will have a greater erection multiple when flaccid, while a larger penis will have a smaller erection multiple when flaccid. People often only notice the size difference in the flaccid state (such as secretly comparing with people around them in public baths or locker rooms), but they don't realize that this difference will disappear or be greatly reduced in the erect state.

Don't think that the stronger and taller you are, the bigger your penis will be. Of all the organs of the body, the stem has the least constant relationship to the development of the whole. The reality is that the size of the penis has no direct relationship with body weight or physical strength. Therefore, having a thick frame and strong muscles does not necessarily mean a big penis. On the contrary, people with a small or thin frame do not necessarily have a small penis when it is flaccid. Of course, just like people's height, weight and body shape, people's penises vary greatly in length, thickness and size. This difference is mostly determined by genetic factors, and is also related to age, region, height, weight and testicle size. Some experts have suggested that a penis that is shorter than 5 cm in a flaccid state and no longer than 8 cm when erect can be considered short. But this should not be confused with micropenis caused by developmental abnormalities. The former belongs to individual differences within the normal range. As long as the erection is normal and is supplemented by appropriate sex education, the requirements of a normal sex life can be fully met. Some scholars have investigated the penises of more than 800 normal men in my country, and found that the lengths of their penises in a flaccid state ranged from 4 to 12 centimeters, which is a huge difference. However, they all have normal sexual life and fertility. For men whose penis is indeed small but whose sexual development is normal and which belong to normal differences, it is important not to carry the burden and to enhance their self-confidence. True micropenis is the result of congenital developmental abnormalities, usually referring to a penis that is less than 2.5 cm in stretched length before puberty and less than 5 cm after puberty, and is accompanied by abnormal development, no erectile function, underdeveloped secondary sexual characteristics, sexual dysfunction, infertility, and no sperm production. For patients with micropenis, drug treatment before puberty is expected to bring some improvement. However, drug treatment in adulthood is no longer effective, and they can only use some temporary alternative methods to help the penis gain a certain degree of sexual intercourse ability. '

Therefore, men who often worry about the size of their penis can put down their psychological burden!
