Girls' bodies change significantly during puberty. Sex characteristics and organs typical of women develop. Some of them (primary sex characteristics such as the ovaries) are present from birth but change. Others only develop during puberty (secondary sexual characteristics, e.g. breasts). With puberty comes a time for young people in which they have to familiarize themselves with their changed body and the new, unfamiliar body feeling.

The vulva is the term used to describe the external sexual organs of women - this includes internal and external "vaginal lips" (vulval lips, Venus lips, labia), clitoris (clitoris) and the vaginal entrance. The boundary between the inner and outer sex is the hymen ("vaginal membrane", hymen). The vulva looks different in every woman.
- Outer "vaginal lips" (labia): The outer labia extend from the pubic mound (pubic mound) to the perineum. They consist of adipose tissue, contain many nerves and are well supplied with blood - and therefore sensitive to touch. The outer labia swell when sexually aroused.
- Inner "vaginal lips" (labia): The inner lips are also sensitive. They lie between the outer "vaginal lips", are somewhat puckered and can be of different sizes and colors (e.g. pink or dark red). They can also protrude beyond the outer ones.
- Clitoris: The visible part of the clitoris, the tickle areas, is where the inner "vaginal lips" meet. A large part of the clitoris runs under the "vaginal lips". The clitoris is also very sensitive, has erectile tissue and many nerves. When sexually aroused, it becomes larger and swollen. The small glans protrudes from under the clitoral hood.
- Hymen (vaginal membrane ", hymen):There are many myths about the hymen. The thin skin flap surrounds the vaginal entrance from the inside, but does not close it completely, so that, for example, blood can drain off during the menstrual period. It serves as protection. Later this function is taken over by the so-called white flow and the hymen becomes thinner. The hymen can look very different and have a different size opening or even not exist at all. It can bleed during the first sexual intercourse (vaginal sex) - for example if it ruptures (defloration). For some girls, the first time they have sexual intercourse (vaginal sex), it can tear a bit and a few drops of blood appear. This does not happen with other girls and the hymen just pushes on its side as the vagina picks up the penis. The hymen usually does not tear during exercise.Even small tampons or standard tampons usually do not hurt it. Further information on the hymen is available on the website of the Austrian Society for Family Planning (flyer in several languages).
Under the urethral opening is the vaginal entrance, which is only visible when the legs are spread. The vagina is one of the internal genital organs. It is about ten to twelve centimeters long and tubular and establishes the connection to the uterus. The cervix, which protrudes into the vagina in the shape of a peg, connects to its upper edge. During the menstrual period, blood flows from the uterus through the vagina. During childbirth, the vagina is the birth canal through which the baby is “born”. The vagina has many folds and is very flexible. The lower part of the vagina is sensitive to the touch. The vagina has an acidic environment (around pH 4), so that there is a certain protection against the colonization of bacteria. The healthy vaginal flora serves as protection against infections.
Note However, this cannot prevent sexually transmitted diseases. Here, among other things, the correct use of a condom is important!
The use of washing lotions, vaginal douches, etc. in the vagina is not necessary for a healthy woman. On the contrary: These can damage and destroy the vaginal flora. When a woman is sexually aroused, the vagina becomes wetter. Special fluids that are formed by the body are increasingly released in the vagina (lubrication).
The uterus is also one of the internal genital organs. It lies between the urinary bladder and rectum. At the upper end the two fallopian tubes open into the uterus. The exit from the cervix and the cervix. They open into the vagina. The uterus resembles an upside-down pear, has a strong muscle layer and is very flexible - just like the cervix. About every month in a sexually mature girl, the lining of the uterus builds up anew inside the uterus and, if no fertilized egg is implanted, it is shed - menstruation occurs. However, if a fertilized egg becomes embedded in the lining of the uterus, pregnancy occurs and the baby grows in the uterus.

Ovaries & fallopian tubes
The two ovaries are also part of the internal sex organs. The egg cells mature in them. They also produce sex hormones (especially estrogen and progesterone).
An egg cell normally grows in one of the ovaries during the menstrual cycle, which is picked up by the fallopian tube funnel after ovulation and transported to the uterus through the fallopian tubes (tuba uterina). The two fallopian tubes are directly connected to the uterus. In the fallopian tube, the egg cell is normally capable of fertilization approx. 24 hours after ovulation. That is, it can be fertilized by a sperm cell if a girl has or had unprotected sexual intercourse with a boy.
Danger! Danger! Sperm cells survive in the uterus and fallopian tubes for a few days. In order to prevent an unwanted pregnancy, it is best to always use contraception - for example at the end of your menstrual period.
