How big is a boy's penis?

The length of the penis is an issue that many men are very concerned about, because the length of the penis is also related to the quality of people's sex life and men's self-esteem. The length of the penis will be affected by many factors. For example, the length of the penis is different for different races, which is also directly related to people's development level. The growth rate is also different. So how big is the boy's penis in life?

1. What is the standard size of a man's penis? This is a question that many teenagers and even adults often worry about. When a boy is born, his penis can be up to 2.5 cm long. In the next two years, the growth rate is relatively slow, and it can grow by 0.5 cm. From the age of 2 to 11, it only increases by 0.2 cm each year. Only after entering puberty, the growth rate will accelerate rapidly, and it can reach the adult level within 5-6 years.

2. The length of the adult male penis varies according to different races. The average length of North American races is 12.8 cm. The Chinese Medical Association's Men's Department has measured the length of the penis in multiple reproductive centers in China, and a length greater than 9 cm is considered normal. The penis is measured using a ruler from the base of the penis, the pubic symphysis to the glans penis. One method is to measure the length of the penis when stretched, and the other is to measure the length of the penis in an erect state.

3. From the perspective of female pleasure, the erection hardness of the penis is more important than the size. And a large penis is not necessarily a good thing. If it is too majestic, it will cause pain to women. In this case, it is best to apply lubricant before sex, so that sex can be more comfortable and smooth, adding more pleasure to sex and preventing pain.

4. In medicine, if the penis can reach 8 cm when erect, it is considered the standard size and is considered normal! For a short or dissatisfied penis, the only effective way is surgery, which is the consensus of the medical community. However, it is not advisable for some men to undergo surgery to satisfy their self-esteem. Whether the penis is bigger or smaller, as long as it does not affect sex life, it is recommended not to undergo surgery!
