What’s it for?
The vagina is your very elastic inlet and outlet valve. You can put so many things inside it, yet so much can come out of it. Pretty amazing! Things that go in:
- Objects like dildos and vibrators (see ‘What not to put inside your vagina‘)
- Tongues (mind the teeth)
- Your doctor’s speculum
- Tampons (learn more about tampons here)
Things that come out:
- Vaginal secretions (creamy fluid, lubrication, discharge)
- Urine (out the urethra, which is nestled just above the vagina)
- Menstrual blood
All vaginas and vulvas are slightly different, just like every face is different, but the main bits are always the same (unless you have an anatomical abnormality).
Here’s the rundown:
Vagina – this refers to the hollow, muscular tube that penises and toys and fingers go into, and that fluids and babies come out of. It is just longer than the middle finger, and ends at the cervix, but it changes size considerably depending on the circumstances: normally it is slightly clenched, but sexual arousal opens it up somewhat, and childbirth unfolds it completely. It is moist, elastic muscular tube. (Read about vaginal tightness and looseness here)
Vulva – this refers to your ‘outer genitalia’ which means your vaginal lips, the labia majora and the labia minora. These lips protect the vagina, but also provide sexual pleasure when touched correctly and stimulated during penetration.
Labia – these are your flappy bits, with the labia minora the biggest, largest lips that protrude from thicker outer lips, the labia majora. Your labia fill with blood when you are turned on, which helps to make sex better by providing a sensual cushion and protecting against damage. The inner labia often (but not always) protrude somewhat from the outer labia, with the inner and outer labia made from different cells. The outer labia contain fat cells (to protect), whereas the inner labia are made out of the same cells as testicles, and are much more sensitive. The outer labia are not moist, but the inner labia (inside) are generally gently moistened by normal vaginal fluids. When aroused, the inner labia fill with blood and may slightly part.
Cervix – this is the entrance to your uterus (womb), and is at the top of your vagina. This is what you can sometimes feel as the end of the line. Nothing much gets through it, and you can’t ‘lose’ anything up there. It might get stuck for a while, but it can’t go travelling through your body wreaking havoc. (See how to check out your own cervix and how to care for a normal cervix.)
Clitoris – this is the big organ that looks small, and swells up with blood when you are aroused. The clitoris, as you can see in one of the diagrams, is actually quite big, and is what they think the ‘g-spot’ actually is: the other side of the clitoris. The clitoris is the essential ingredient for sexual stimulation and orgasm in most women, and as you can see in some of the diagrams, has arms. The clitoris swells with blood and becomes erect just like a penis does. Read more about the clitoris and see pictures here.
Uterus – The uterus (or womb) is a triangle-shaped, hollow muscle that grows endometrial cells on the inside. These endometrial cells ‘bloom’ every month and are what would feed a growing fertilised egg, supporting the growing baby. If you don’t get pregnant, this lining sheds in what is known as your menstrual period. The endometrium is also prone to disorders and disease, since it is affected by hormones.
Fallopian Tubes – the fertilised egg leaves the ovary it came from, and travels down the fallopian tube to the uterus. Eggs are actually fertilised in the fallopian tubes, not the uterus. These tubes are about as big as a piece of skinny spaghetti.
Ovaries – Your ovaries release an egg every month when you ovulate (mid-cycle, the magical ‘Day 14’). This egg travels down the fallopian tube into the uterus. If it’s fertilised, it will try to implant on the wall of the uterus, but if it isn’t fertilised (most of the time), it simply gets reabsorbed into the body and is excreted out with your menstrual period (blood) as the endometrium sheds.
Mons pubis – this is the name for the pubic bone that shields the entire vagina, and upon which pubic hair grows.
Hymen – the hymen is a thin covering of the vaginal entrance most commonly found in younger girls, but which may persist until adulthood in the absence of sexual intercourse, use of tampons or other activities (sports, horse-riding, etc.) that may stretch the opening. Read about the hymen here.
Urethral opening – the urethra is the tube that carries your urine from your bladder to the toilet, with the opening sitting inside the vulva (see diagrams).
