The TGIF Sex Blog [Vagina]

¡Hola! Everybody…

OMG! I’m sorry people, I have to say that Palin gives women all over a bad name. Did you see the second Katie Couric interview?!! Utterly, painfully clueless… Someone described Palin as “Bush with tits.”

Speaking of cunts…

Eve Ensler, Vagina Monologues

Pussy, cunt, chocha, toto, beaver, the jade throne -- whatever you call it, the vagina has had a pivotal role in human history. Despite its crucial historical location, you might as well have been talking about the dark side of the moon when talking about what we knew of the vagina. This changed somewhat during the late 1950s and early 1960s when William Masters, M.D., and Virginia Johnson devised an experiment that allowed them to observe directly what happens deep inside the vagina during sexual arousal and intercourse. They did this by having women masturbate to orgasm using a camera-equipped plastic penis, complete with a special (cold) light to illuminate the mysterious, lightless interior.

They reported that the vagina is “a potential rather than an actual space” -- its soft, velvety walls (yummy) are collapsed together, touching each other. However, during the first stage of the sexual response cycle, shortly after initial sexual stimulation, two things happen: the vagina begins to lubricate and to expand. According to researchers, vaginal lubrication is the first physiological sign of arousal in women: within 10 to 30 seconds after stimulation begins, the researchers found, little beads of fluid begin forming all over the vaginal walls, giving them the appearance of a sweat-beaded forehead. The little beads rapidly spread to form that deliciously smooth, glistening covering men love so much.

[Note: for the sake of brevity I am using the accepted “stage model” of orgasm. I have problems with this stage-model (as do others) but I am using this model now only because it’s more convenient for my purposes today.]

As a woman becomes increasingly aroused, the deepest two-thirds of her vagina begin inflating, almost like a balloon -- lengthening and expanding in what Masters and Johnson described as a “tenting” effect. The uterus and cervix pull slowly up and back, out of harm’s way. (Some women have retroverted, or tipped, uterus, causing the cervix to stay where it is, suspended in this widening vaginal cavity -- where a man’s penis may batter it, sometimes painfully, during intercourse.)

During all this, the vaginal walls dramatically change in color form their usual purplish red tint to a distinctly darker purplish hue. This is the result of vasocongestion -- the damming up of blood that’s the central event of sexual arousal.

As sexual excitement reaches the plateau stage (the second stage of the sexual cycle), the outer third of the vagina swells as it engorged with blood, to the extent that it actually narrows the vaginal entrance by up to 50 percent. (The deeper part of the vagina is expanding; the outer part is narrowing.) Masters and Johnson called this outer third the “orgasmic platform,” and it was this area that reacted most dramatically during orgasm. At the moment of climax, this whole outer ring begins spasmodically contracting at 0.8-second intervals, anywhere from 3-15 times. At the very highest level of sexual excitement, some women experience a sort of superorgasm: the orgasmic platform explodes into a spastic contraction lasting 2 to 4 seconds (knocking them knees! LOL!), then downshifts into the 0.8-contractions of “normal” orgasm.

After, during the third (“resolution”) phase of the sexual response), the orgasmic platform rapidly drains of blood, the vaginal opening expands, and the inner, distended part of the vagina shrinks back to its original state.

Whew! LOL

These findings point to one erroneous, but common, misconception men have about the vagina: that it’s deep, pounding penetration that drives women wild. Much of this misconception is the result of male-oriented erotic material that emphasizes the imagery of deep penetration: spikes, spears, lances, swords all plunging to the hilt.

But the truth is that for most women, the deepest two-thirds of the vagina are practically numb to the touch. Researchers have found that deep inside, the vaginal walls have few nerve endings. By contrast, the outer third of the vagina and the vaginal opening are exceedingly sensitive to touch.

On the other hand, more recent research have established that some women do find deep vaginal penetration incredibly pleasurable, reporting that it triggers a “deep” orgasm that’s different from an orgasm touched off by clitoral stimulation. Because the vaginal walls have so little feeling, sex researchers believe that some women enjoy the deep muscular contractions of the uterus and muscles of the pelvic floor (this can also be due to the more recently discovered “clitoral wings” that form a semi ring extending close to the anal area). Other women seem to be especially responsive to firm pressure on top of the front wall of the vagina, also called the G-spot.

I guess what I’m saying here is that basically when it comes to sexual enjoyment -- and sexual equipment -- all women are alike… but also different.
