So first, the Vulva.
When people refer to the "vagina," what they usually mean is the vulva, which includes all the external parts, including the inner and outer lips. They're called the labia majora (the outer set) and minora (the inner set). A lot of people refer to these colloquially as "lips" because that's kinda what they look like.
Labia Majora - Outer Lips.
These are the first lips you see, and hair grows on them naturally. The labia majora's job is to protect the more sensitive parts inside. This is also where the sweat glands live.
Labia Minora - Inner Lips.
Is the second layer of protection for the openings, and they also have glands that secrete lubricant to keep you comfortable.
It is important for me to point out that the lips might not be symmetrical, they might extend beyond the labia majora and the end might not be totally smooth, and that's okay! It's totally normal! You're normal! What is important for you to understand is that the Labia is as unique as our fingerprints. We’re all different down there. There is no right or wrong about it.
Clitoris and Clitoral Hood.
Oh! that tiny little nub that can bring so much pleasure has 8,000 nerve endings. That's why it is super sensitive, and for many of us, fairy stimulation and is the best way to orgasm.
The hood, that flap of skin that slides back and forth, is there to protect the clitoris and prevents irritation and arousal when you don't want it.
Urethra.
Small opening to allow urine to come out. It is right below the clitoris. It's hard to see, and you can't really feel anything there. And, no, pee doesn't come out of the vaginal opening! Don't be fooled!
Vestibule.
The Foyer. The lobby leading to the vagina, which is inside your body. We should also say here that there are many color variations in the whole external vulva area, depending on your skin tone and whether or not you're sexually excited. So, remember, your normal is the only normal you should care about!
Internal Clitoris.
This will blow your mind away! The Internal Clitoris is a recent anatomical discovery. You have a wishbone-shaped structure extending from your clitoris on the outside of your body- consider that as the top of the wishbone- to the area under your labia majora- deep inside. It's basically like a tissue that engorges during sex and its fairly excitable. Which means there’s literally much more to our sexual excitement than meets the eye ;-).
Vagina.
I trust that by now you probably understand that the whole thing is not exactly a “vagina”. The vagina is actually the birth canal leads to your uterus. Some think of it as a tobe that is always open but that is so further away from what actually happens.nIts a muscle, that, when at rest, is in fact closed! The vagina walls touch unless there’s a tampon or a finger or something else inside ;). Also, nothing can get lost up there before the vagina is an enclosed pouch like that doesn't lead to the rest of your body. Oh, and it's normal for the vagina to feel bumpy to the touch.
Cervix.
Its a neck-like part of your uterus that extends into the vagina.Its the place where you gyno takes a sample for a Pap smear (which you should do regularly!)
It's also the part that opens up and dilated right before we give birth. Otherwise, it says closed only to release a small opening during your period days to give the blood room to flush out.
Uterus.
The magic kingdom where the fetus would live should you get pregnant. It sheds its lining every 28 days or so were there no pregnancy, also known as your period.
Fallopian Tubes and Ovaries.
Every month your ovaries shoot out an egg and send it floating happily down the uterus, where it will hang out in hopes of meeting up with some sperm to make a little monster ;).
So, there you have it.
