Why do people have pubic hair?

Pubic hair is vital to the human body. Not only can it block the growth of many bacteria and viruses, but the most important thing is that it indicates that people have entered puberty. It can be of certain help in the process of sexual life, appropriately reducing friction and pain, and can achieve a ventilation effect. Especially for female friends, pubic hair becomes more important and should not be shaved easily.

Pubic hair is the hair that grows on the human genitals. When teenagers enter puberty, due to the secretion of estrogen and androgen, pubic hair begins to grow on the genitals and becomes thick and curly.

Male pubic hair grows at the base of the penis, pubic area, and inner thighs, forming an inverted triangle. Female pubic hair grows on the labia, pubic area, and inner thighs, forming an inverted triangle.

Pubic hair is a normal sign of human health.

Pubic hair is not useless, but grows to protect our bodies. Pubic hair can absorb the sweat and mucus secreted from these parts and dissipate them around, which is beneficial to physical health. During sexual intercourse, it can also increase the pleasure caused by friction on the external genitalia. In addition, pubic hair also has the function of keeping warm, protecting the normal survival temperature of sperm and eggs.

Reduce friction and pain

In addition to being a sexual characteristic, pubic hair can also reduce friction and pain caused by rapid movements during sexual intercourse. In addition, the sweat gland ducts in the human pubic area are relatively large and abundant, and the amount of sweat is high. In addition, the hidden location makes it prone to poor ventilation. The presence of pubic hair can play a role in "ventilation".

Pubic hair is a secondary sexual characteristic of humans. During female puberty, there are two more prominent developmental characteristics: one is breasts, and the other is the growth of pubic hair.

The growth of female pubic hair is divided into six stages:

In the first stage, before the age of 10, there is no visible pubic hair.

The second stage, around 10-11 years old, is when pubic hair begins to grow sparsely, long, and soft, and is slightly curly.

The third stage, from 12 to 13 years old, is when the pubic hair increases in number and gradually becomes curly, thicker and darker in color.

Stage 4, 14-15 years old, pubic hair expands to cover the labia.

The fifth stage, 16-17 years old, the pubic hair expands to the pubic area and becomes adult type.

In the sixth stage, at the age of 18, the pubic hair is distributed in a typical inverted triangle shape to the inner thighs.
