What are the characteristics of female physiological labia? The labia minora of women varies depending on their age group, and after multiple sexual intercourse, girls who have not yet developed well are very soft.
The front end of the labia minora merges with each other and is divided into two leaves. The front leaf wraps around the penis to form the foreskin, while the back leaf forms the penile frenulum. The posterior end of the labia minora combines with the posterior end of the labia majoris, forming wrinkles in the midline and forming a frenulum of the labia minora, which is prone to tearing during childbirth. Unmarried and married women, the closure of the labia minora serves to protect the vagina and internal genitalia, and is a part of women's natural defense function. The labia minora is soft and free of subcutaneous fat, with abundant sebaceous and sweat glands. The surface is moist and smooth without hair. There is a rich distribution of nerves under the mucosa, and the sensation is very sharp. The labia minora is thin, and its size and shape vary from person to person. Some asymmetry, large and small, is normal. The labia minora is located on the inner side of the labia minora and is also a skin wrinkle. There is no growth of pubic hair on it, and the surface is smooth and delicate, with rich elasticity. It is mostly light red, moist like mucosa, and distributed in sebaceous glands.
Subcutaneously, there are blood vessels, elastic fibers, and a small amount of smooth muscles, with abundant nerve distribution and keen sensation. There are significant individual differences in the shape and size of the labia minora, with some having narrow labia minora and others having long labia minora perpendicular to the outer side of the labia minora. Some are very thick, some are very thin, some are as large as irregular umbrella shaped nail caps, and some are like typical semicircles. Some people have a light red color, some people have a brownish red color, and some people have two colors for their labia minora: the outside is brownish black, and the inside is pink. Generally speaking, its color will deepen with age and the number of deliveries. Some women in African tribes take pride in the length of their labia minora and have been using it since childhood. As adults, their labia minora is thick and long, reaching high above the labia minora, but its size has no significant impact on sexual response. Obviously, the degree of sexual tension experienced by individuals through sexual skin provides satisfactory clinical evidence, and color changes are directly proportional to an individual's response to specific sexual stimuli. It must be emphasized that the occurrence of sexual skin reactions is a sign of approaching clinical orgasm. Among all women who observed the release of sexual tension during orgasm, it can be proven that the color of their sexual skin has changed. During the disappearance period, the color of the labia minora rapidly disappears from a dark or bright red color to a light pink color.
The second stage of color disappearance (complete restoration to an unstimulated state of color) is also rapid, but not so regular. If the color changes experienced by sexual skin are inconsistent and disappear, the appearance of the skin will become speckled. After changing the plateau color of the labia minora, the diameter increases by at least twice, which helps to open the vaginal opening. In addition, sexual skin coloring not only indicates a strong level of female tension, but also has become an upcoming clinical indication for orgasm while maintaining effective sexual stimulation. Whether it is a premenopausal or a parturient, after entering the sexual arousal period, the labia minora becomes congested and swollen, with a significantly enlarged diameter, which increases to 2-3 times during the plateau period. As the diameter increases, it protrudes from the protective labia majoris barrier, and the effective length of the vaginal tube during sexual intercourse is extended by at least 1 centimeter, which helps to open the vaginal opening.
After the diameter increases, the labia minora prepares for the most unique female physiological response (color change). During the platform, almost all women's labia minora showed bright color reactions. The postpartum woman changes from pink to a bright red, spreading around the outer opening of the vagina, including the foreskin of the penis. The color of the postpartum woman changes from bright red to deep purple. As a rule, the darker the color change of the labia minora, the more severe the degree of pelvic and labial varicose veins. Due to the unique color changes during the plateau period, the labia minora in a state of sexual response is called sexual skin. Premenopausal women who reach a plateau level of tension and experience changes in sexual skin color experience the process of orgasm.
In order to support the above discussion, it must be assumed that specific forms of effective stimulation of sexual skin color changes will not continue to undergo significant changes (the sexual skin mentioned here specifically refers to it and cannot be confused with the skin color changes of female monkeys and orangutans during estrus). Removing effective sexual stimulation cannot achieve orgasmic release, and the color change of the labia minora also quickly disappears, which is faster than the increase in labia diameter caused by sexual tension.
