Thursday is Vagina Day

You may have noticed that we've been blogging a lot about penises lately. In the interest of equal time, Superblog!! hereby announces that Thursday is Vagina Day!

Now, you may be wondering just what a vagina is. Luckily, Wikipedia has you covered:

The vagina (from the Latin for "sheath" or "scabbard" ) is the tubular tract leading from the uterus to the exterior of the body in female mammals, or to the cloaca in female birds and some reptiles.

Specifically, in human females:

The vagina is an elastic muscular tube about 4 inches (100 mm) long and 1 inch (25 mm) in diameter that connects the vulva at the outside to the cervix of the uterus at the inside.
[...]
The vaginal opening is at the back (caudal) end of the vulva, behind the opening of the urethra. The inside of the vagina is usually pink, as with all internal mucous membranes in mammals.

(In common speech, the term "vagina" is often used improperly to refer to the vulva or female genitals generally; strictly speaking the vagina is a specific internal structure and the vulva is the exterior genitalia only. Calling the vulva the vagina is akin to calling the mouth the throat.)

The vagina can perform the following tasks:

Provide sexual pleasure to a woman (although vaginal orgasms are rarer than clitoral orgasms).

Admit the penis of the male for sexual intercourse and ultimately the introduction of male gametes (sperm) for the fertilization of ova.

During live birth, provide the route to deliver the fetus from the uterus to its independent life outside the body of the mother. During birth, the vagina is often referred to as the birth canal.

Provide a path for menstrual fluids to leave the body.

Some erotic performers, particularly in Asia, can use vaginal muscles for tricks, such as smoking or playing musical instruments.

Wow! Who knew that a vagina could do so many different things? Smoking! Making babies! Bringing peace to the Middle East! Is there anything a vagina can't do?

We'll return to this subject later, I expect. Because... Thursday is Vagina Day!
