The length of men's "there" has been concerned since ancient times. Some men, out of curiosity, will secretly compare the size of their penis with those around them in the bath. Once they find their penis is short, they will have inferiority complex.
In fact, there are many differences between a man's penis and his stature, fat and thin, as well as his facial features. In 1950, the penis size of 1412 healthy young men was measured in China. The results show that in normal state, the longest is 14.5 cm, the shortest is 4 cm, and the average is 8.375 cm; The average circumference is 8.3 cm; The average time of erection is 12 cm. This figure became the basis for domestic condom manufacturers to classify models at that time. In 1990, relevant experts measured the penis of 2547 male college students aged 16-40 years old. The average length was 7.43 cm and the average circumference was 8.17 cm; The average time of erection is 13.34 cm. Other studies have pointed out that the average length of Chinese male penis is 8.08 cm, the circumference is 8.11 cm, and the average effective length of erection is 12.4 cm. These measurement results are related to the selection of objects and measurement methods, so they can only be used as a reference. In addition, the penis length of the same person is not constant under normal conditions, such as tension, cold or severe fatigue, which can shorten the penis.
