When we talk about the private parts, we mostly refer to the female vulva and vagina. In a strict sense, the female private parts refer to the female reproductive system. It includes the internal genitalia consisting of the vagina, uterus, fallopian tubes and ovaries, and the external genitalia (i.e. vulva) consisting of the mons pubis, labia majora, labia minora, clitoris and vaginal vestibule, as well as their related tissues. The vulva (external genitalia) 1, the pubic mound: the pubic mound, in front of the pubic symphysis, is an inverted triangular mound of elevated parts, also known as the “triangle”. After puberty, pubic hair will grow in this area. The mons pubis is plump and elastic, and its rich fatty tissue and pubic hair can play a role in supporting and shock-absorbing cushioning during sexual intercourse, and rubbing the mons pubis can also get a certain amount of sexual pleasure. The pubic hair also has a certain role in blocking the invasion of external harmful substances, sparse, color, volume and straight is different from person to person. 2, labia: the mons pubis down is the outer layer of the labia majora and the inner side of the labia minora, each divided into two pieces, like two doors to protect the innermost vagina and urethra. The labia majora are the most loyal “guardians” of the urinary and reproductive system, resisting the invasion of viruses, bacteria and various microorganisms, and also acting as a cushioning spring during sexual intercourse. The labia minora protects the vagina and internal genitalia, and is part of the natural defense function of women, strengthening the defense protection. The color, thickness and symmetry of the labia vary from person to person and are influenced by genetics and hormone levels, so as long as there is no itching, pain, odor or abnormalities affecting life, there is no need to worry. 3, clitoris: The clitoris is shaped like an upside down “Y” and is homologous to the male penis in terms of tissue structure. The clitoris is located at the top between the labia minora on both sides and is usually protected by the clitoral foreskin, while the clitoral head becomes erect when sexually excited and is the main source of sexual pleasure (more than twice as sensitive as the penis). Internal genitalia 1. Vagina: As the name suggests, the vagina is a channel connecting the uterus to the vulva, the female organ of sexual intercourse, and the channel through which menstrual blood is discharged and the fetus is delivered. If you open the labia majora and minora, you can see the vaginal opening below the urethra and the hymen with irregular holes on the inside of the vaginal opening. In its daily state, the vagina is about 8-12 cm deep and 1-2 fingers wide, while during sexual excitement the vagina extends to 15 cm. The vaginal nerve endings are mainly located near the 1/3 of the vaginal opening, where frictional stimulation can produce sexual pleasure, while the deeper 2/3 has almost no nerve endings and is only sensitive to deep pressure. 2. Uterus: The vagina goes further inwards, through the cervix, to reach the slightly flattened inverted pear-shaped, muscle-based uterus (the penis cannot enter). It is the place where menstrual blood is produced and where the fetus is conceived during pregnancy. 3, fallopian tubes: The fallopian tubes are long, thin, curved tubes on each side of the uterus, connecting the ovaries and the uterus on both sides. The fallopian tubes are both the place where the egg meets the sperm and the channel for transporting the fertilized egg to the uterus. The ovaries are a pair of flat, oval-shaped gonads that produce and discharge egg cells and secrete estrogen. There is no need to be shy or feel inferior about understanding your private parts and talking about them. It is as much a part of the female body as any other organ you have. By fully understanding this somewhat special and important part of your body, you can take better care of it and appreciate it.
