In women's childhood, the two labia are closely combined with a slight gap between them. After puberty, pubic hair begins to grow on the outside of labia majora, and the inside is smooth and moist. After entering puberty, there will be slightly protruding spots on the inner side of the labia, which is the oil gland. These glands secrete oil to keep this part lubricated.
The labia minora, which is also divided into two parts, is the second pass to protect vagina and urethra. The labia minora is not obvious in childhood, and it begins to increase in adolescence. The labia minora is smooth and moist inside and outside, with abundant nerve endings, which is one of the sensitive areas. When sexually excited, the labia minora is congested and swollen, and its volume can be increased by two to three times, which can increase the effective length of vagina by more than one centimeter.
Every woman's labia are different. Most women's labia majora is larger than labia minora, but there are exceptions. Individual labia minora is larger than labia majora, or two labia minora are different in size. This is a normal phenomenon and will not affect sexual life and reproductive function. Some people need labial plastic surgery, probably because the labia minora protrudes, causing pudendal discomfort. Pay attention to wearing loose underwear as much as possible.
The labia minora is located inside the labia majora, which is also a skin fold. There is no pubic hair growth on it, and the surface is smooth, delicate and elastic, mostly reddish and moist as mucous membrane, with sebaceous glands distributed on it. There are blood vessels, elastic fibers and a small amount of smooth muscle under the skin, as well as rich nerve distribution, which makes you feel very keen. There are great individual differences in the shape and size of labia minora. Some people have a narrow labia minora, while others have a long labia minora that hangs to the outside of the labia majora. Some are thick, some are thin, and some are irregular umbrellas; Some are as big as nails, and they are typically semi-circular. Some people are reddish; Some are brownish red; Some people even have two colors of labia minora, brown and black on the outside and pink on the inside. Generally speaking, its color will deepen with age and delivery times. Women in some tribes in Africa are proud of the length of the labia minora, so they pull it from an early age, so the labia minora is thick and long in adulthood, protruding beyond the labia majora, but its size has no obvious influence on sexual life.
