Everyone is different. It's just how it is.
There are two sets of labia - the labia majora and the labia minora. The labia majora protect the genitalia that lie within them. The labia minora secrete chemicals that lubricate the genitalia and that kill bacteria to prevent infection.
The size, color and texture of labia vary from woman to woman. There is no 'normal' standard because of genetics. It would be like asking what is the cause for a long nose. However, friction from various activities, both sexual and non sexual can effect the size, color and texture of both the labia majora and labia minora. This is why some women have very small pale labia and others have very large, protruding, heavily textured/wrinkled labia.
For some women, having enlarged labia minora (inner genital lips) can be functionally or emotionally bothersome. Thus, labial rejuvenation fixes this problem
The labia are like any other part of the body and have no standard size or definition of size. Like the nose, mouth, ears and eyes they can be all varieties of sizes and colors. While some women have very small labia minora that are not visible between the labia majora, others have labia so large they not only protrude but hang down from between the labia majora. It is worth mentioning that in many cultures larger labia are considered attractive, the larger the labia the more appealing the woman is considered.
The only time women would be missing one of their labia is if they have had it surgically removed. All cis-women have two inner labia and two outer labia.
Majora, yes, Minora, probably not. The baby stretches things out quite a bit. Don't get self conscious about it though. A woman's body is beautiful and this is just a sign that she has given the precious gift of life.
While genetics control the various sizes of the human anatomy, like other parts of the body, the labia can be manipulated and altered by various methods of use. They can be lengthened, thickened, tanned and bleached.

It's when a woman is "turned on" that it becomes enlarged. More blood flow to the area causes the swelling. Arousal can enlarge a woman's inner AND outer (more common) labia. There is more. However, the questioner didn't ask why labia are enlarged during sex. Labia will get larger as a girl goes through puberty. A girl will appear to have no labia, or exceptionally small labia until puberty. Depending on genetics and nationality, women's inner labia have been measured at 1 inch, outer labia have been measured to be as long as three inches, unaroused. Also, it is accepted practice in many cultures for women to stretch their labia by attaching weights. This practice is becoming more common in western society. Devices are sold on the web for stretching labia. Oral sex can elongate labia, too, if the person sucks and stretches the labia regularly. In the U.S. a small number of women have their labia surgically reduced in size, but recent evidence suggests that more women and their partners prefer longer labia because of the sexual stimulation provided to the male and female. Some believe this is all part of an increased focus on females being more interested in sexual gratification during sex , i.e.; over 50% of women 40% of men from 18 to 45 report shaving all or most of their pubic hair to enhance sexual arousal, improved cleanliness and because of how bare genitals can enhance fore play and arousal..
yes
That is what you see on the outside if you look between her legs. It contain labia's and the clitoris, the vaginal entrance and the urethral entrance. Many calls it the vagina but itś the inside that is called the vagina.
Yes. Over time, it will get darker with age as it will grow larger and is exposed to more air. women who sunbathe in the nude will have a much darker labia as well. If you need more information on this, ask your gynecologist on your next visit.
