How big and long is a man's bottom?

The length of a man's penis is directly related to his sexual function. Generally speaking, men with longer penises have stronger sexual functions and are more likely to give women pleasure. If a man's penis is not long enough, his sexual function may be poor, which will not only make women unsatisfied, but also make the man feel inferior. So, how big and long is a man's penis?

Whether the length of the male penis is appropriate determines whether the sex life is satisfactory. It is a way of communicating intimacy. Emotions, a healthy body, humor, etc. are all catalysts for sex, not just a large penis. Below, the editor will popularize the normal length of the male penis for you. If you want to know whether you are qualified, come and have a look.

What is the normal length of an erect penis?

The length of a man's penis is divided into two parts: the outer part and the inner part. The length of the penis should be measured when erect. For men with a fatter body, the penis will appear smaller due to the more subcutaneous fat. In addition, there will be a certain deviation between the length measured when sitting and when standing, which also depends on the subcutaneous fat in the abdomen.

The longest penis of Chinese men in normal state is 14.5cm, the shortest is 4cm, and the average is 8.375cm; when erect, the longest is 16cm, the shortest is 9cm, and the average is 12cm. When measuring, please note that the measuring tape should be tightly pressed against the pubis, the penis should be flattened, and the distance from the pubis to the glans penis is the penis length.

When men are having sex, the most sensitive part of the female vagina is the outer 1/3. The length of the vagina of Chinese women is generally 8 to 9 cm, which means that if your penis can be ≥ 3 cm in an erect state and has a certain diameter, you have the conditions for a satisfactory sex life. The penis is an important part of the male reproductive organs and is very important to a man.

In fact, as early as in ancient times, the penis appeared on stone totems, which fully reflected the ancient people's worship of reproductive organs. The size of the penis varies among races and individuals. The length (non-erect) of the penis of Chinese men (18-45 years old) is between 4.5-8.8 cm, with an average of 6.5 cm, an average transverse diameter of 2.5 cm, and an average circumference of the middle part of the penis of 8 cm.

The growth process of the male penis begins to slow down at the age of 20 and basically stops at the age of 25. The penis growth will not exceed 1cm between the ages of 20 and 25.

1. Penis length and genetic factors. The penis, like other organs in the body, has its size and morphological characteristics controlled and influenced by genetic genes.

2. The length of the penis is related to its development and nutrition. Generally speaking, adult males who are physically strong and tall have well-developed external genitalia including the penis and scrotum. Their penis may be larger, while those who are not are smaller. However, it is worth pointing out that the size of the penis is not directly proportional to the height. It is common to see some men who are less than 1.60 meters tall, whose penis can reach more than 18 centimeters when erect.

3. The length of the penis is also related to obesity. Men with fat in the lower abdomen, pubic symphysis, and perineum often have poorly developed penises, which are relatively short compared to normal men. Compared with an enlarged body, this short penis may bring certain difficulties and unsatisfactory sex life after marriage.

4. The length of the penis is also related to other factors, such as endocrine disorders, insufficient male hormone levels, penis retraction caused by swelling of the testicles or scrotum, etc., which may cause a short penis.

What is the normal penis length reference value?

Measurement of non-erect penis length: At room temperature of 18°C, stand upright, lift the penis to 90° with the body, and use a ruler to measure the length from the pubic symphysis above the penis to the top of the glans penis.

Measurement of the length of the erect penis: Stand upright, pinch the glans penis with your hands and pull it forward until it can no longer be extended. Use a ruler to measure the length from the pubic symphysis to the glans penis (the length after pulling is basically the same as the length when erect). A length greater than or equal to 8 cm is normal.

The International Men's Health Organization (MTD) has concluded through nearly 30 years of research:

(Asia) Normal penis length M = (height T-105) * 0.618/3.14 (cm)

Normal penis diameter D = M/3.14 (cm)

(Europe and America = Asia/1.414/0.618)(cm)
