The tube of the vagina itself has very few sexually stimulatable nerve endings deep within (it does have nerve endings that sense pressure, though). The sexual nerve endings of the vagina increase toward the outer end of it and are most concentrated where it curves outward toward the vulvar opening and upward to the clitoris.

The scrotum tissue (but not the testicles) on a man are formed from fetally analogous tissue to the woman's labia minora (vaginal lips). The seam down the middle of the scrotum is where the lips would divide in a woman. The two areas have the same compliment of nerve endings, so asking a woman to have an orgasm from stimulation of her cunt lips alone would be the same as asking a man to have an orgasm from stimulation of his scrotum alone. It CAN be done, but as i said, it is unusual.

Most women achieve orgasm through friction of the clitoris against the man's pubic bone while engaged in intercourse or through stimulation of the clitoris by manual or oral contact.

But Sigmund Freud, the founder of psychoanalysis, claimed that women who had clitoral orgasms were "infantile." He asserted that to be truly mature, a woman must have only "vaginal orgasms." His theory has long been discredited, both psychologically and anatomically. yet some women do report "vaginal orgasms without friction of the clitoris."

To understand this, you have to understand the way the clitoris is shaped and how it is carried in the body.

Most men -- and all too many women -- think that the clitoris is a tiny "button" or "nub" of sensitive flesh located above the vagina, at the level of the base of the woman's pubic bone. This is NOT TRUE.

The clitoris is a shaft of engorgeable tissue, built just like a small penis, with a sexually sensitive head (the glans) at its tip, just like the head of a small penis. It comes equipped with a foreskin or prepuce, just like an uncircumsized penis, and during sexual excitement, the foreskin retracts, exposing the glans of the clitoris, the little "button" most people think is the entire organ.

Unlike the shaft of the penis, which is free-hanging, the shaft of the clitoris lays vertically along the body's midline, covered and never seen, just beneath a layer of fat and skin. The shaft of the clitoris reaches down toward the vagina and then splits to each side.

To imagine this better, remember that the vaginal lips are analogous to the scrotum -- and now think of the way the shaft of the penis emerges from the scrotal area and visualize the shaft of the clitoris (covered beneath a layer of fat and skin) emerging from the top of the vaginal lips and terminating in the little glans, which pokes out of the skin. Got that? Okay. But there's more! When it reaches the body, the tiny clitoral shaft divides into two "forks" or "legs" called crura. (The penis also has two crura at its base, but they are relatively small; they serve to anchor the penis to the body..) The elongated crura of the clitoris extend downward along either side of the vaginal opening and terminate in bulbous glands, so the entire clitoris looks like an upside-down letter "Y" that has been bent forward at the top. And what most people call "the clitoris" is just that end-tip of the letter "Y" shape, the clitoral glans.

Now the big disadvantage to having the clitoris fixed in place beneath the skin with elongated crura is that the woman has little freedom of motion for stimulation. Imagine if the penis was surgically attached to the flesh of the abdomen with only the glans free at the top (right below the belly button) and there was no ability to thrust in and out. A man would be somewhat at the mercy of his partner's technical skill or acquiescence to his limited range of motion -- he'd have to rub his body up and down along his partner's body to stimulate the penis in the same way she rubs up and down against his pubic bone (some men do this when masturbating by rubbing against their mattress) or he would have to ask her to stroke the glans of his penis the way she asks him to stroke the glans of her clitoris.

Sounds like women have a rough go of it, maybe? Like they have a harder time getting off because of the fixed position of the clitoris? Not so!

There is a distinct advantage to having the clitoris fixed in place: any downward pull on the skin covering the shaft and forks of the clitoris is felt directly in the glans, as it is pulled downward through the foreskin. Thus, the friction stroke of a man's penis going into and out of the vagina can, by pulling and releasing the clitoral root and shaft, produce an indirect stimulation of the glans of the clitoris. Many women are capable of having orgasms like this, although the process, being indirect, may take longer than having an orgasm induced by friction stimulation of the clitoral glans itself. Because they do not see the entire clitoris under its covering of skin and fat, many woman (and their male partners) think that they have not stimulated the clitoris (by which they mean only the glans of the clitoris) -- when in fact they have done so -- and thus they buy into the idea that they have achieved a strictly "vaginal" orgasm.

Men, imagine being masturbated by a woman who only plays with the root and shaft of your penis and with the skin of your scrotum, but never touches the tip of your cock. Could you come? Would you come, perhaps after quite a while? It's possible, isn't it?

What you would experience (we could call it a "penile shaft orgasm") would be the equivalent of Freud's "vaginal orgasm."

Do you think this form of sex play would be as pleasurable as having your partner touch or lick the underside of the sensitive head of your penis? Would it be as pleasurable as sliding the glans of your penis into and out of her warm, soft, wet cunt? Is penile shaft stimulation all you'd want every time you made love? Is clitoral shaft stimulation all you'd want your female partner to experience every time she made love with you?

The "vaginal orgasm" (clitoral crura orgasm) exists, as does the "penile shaft orgasm." But neither is greatly sought after by the vast majority of men and women. Most men and most women seek stimulation to the area of the glans of the penis and just below and the glans of the clitoris and just below. And that's why i recommend that in the interest of connubial bliss, men and women ignore the admonitions and instructions of "experts" like Freud and his followers, and do what pleases each other most.

In the words of the old proverb, "What's sauce for the goose is sauce for the gander." That is, men and women are more alike than they are different.

Or, as the Bible says, "Do unto others as you would have them do unto you." In short -- let mutual pleasure be your best and truest guide.

Unfortunately, or so it seems to me, when Freud's ridiculous concept of the "purely vaginal orgasm" was thrown into the dustbin of history (and good riddance!), sexologists began focussing their attention solely on the clitoris. Or rather, on the GLANS of the clitoris. Men were taught to rub and lick the little "button" and assured that this, and this alone, would "satisfy" their partners. Women were told -- especially by a few rabid feminist authors -- that since it was "almost impossible" for a woman to have a vaginal orgasm, the ideal partner-sex for a woman consisted of her being masturbated or licked. The in-and-out-stroke of the penis in the vagina, these writers claimed, was useless when it came to stimulating a woman to climax.

Although this notion -- that penis-in-vagina sex rarely brings a woman to orgasm -- may be true for some women, it is most definitely NOT true for all women, or even the majority. And for a certain number of women, including myself, the most satisfying orgasms (the ones i call the "big baked potato orgasms," the kind that are HUGE and go on and on, ONLY occur during penis-in-vagina sex.

What am i doing that makes penis-in-vagina orgasm so achievable -- and adorable -- for me? Why, i am taking my clitoris on an excursion!

I wish i could draw you a picture here. Let me try in words. The clitoris is a small penis-analogue organ situated above the opening of the vagina. In most women only its tip (the glans) is exposed -- and then only when one retracts the clitoral foreskin or when the clitoris becomes erect and emerges from the foreskin.

Internally, the clitoral shaft has a little bend in it, called "the clitoral knee." If you were to cut a woman's body in half in linear cross-section, the clitoris would look like a crooked little finger, of which only the top joint emerges from the foreskin -- or like a little daffodil that has not yet opened and is bending its flower-bud downward and outward.

The clitoris and vagina embracing the penis during intercourse as seen facing toward the woman. The outer layers of skin, fat, and muscle have been dissected away, and the penis is shown in simplified cross-section for position only. Atop the pea-shaped clitoral glans, normally the only part visible outside the body, you can see the ascending portion of the clitoral shaft. Upon reaching its apex (which Dickinson calls "the clitoral knee"), the shaft bends downward and divides into the two "forks" or crura which encircle the vaginal opening. Drawing by Robert Latou Dickinson, in "Human Sex Anatomy," 1949.

The clitoris is flexible and erectile. During erection it lengthens and its bend flattens out to a greater or lesser extent, depending on personal anatomy, until it resembles the angle of an opened daffodil, still pointing outward, but a bit less downward. Not only is the clitoris itself somewhat flexible, its forked shaft is held in place by tiny internal ligaments that allow it to move up and down the midline of the body, root and all.

The root of the shaft of this little organ sits, in most women, right above the lower portion of the public bone, called the symphysis in medical terminology. From there it divides into the two "forks" or crura, which extend downward around the vaginal opening.

In a cutaway side-view of the body, the symphysis is an oval bone. Its cross-section is shaped like a narrow football's cross-section, with the long axis running more or less up and down, the shaft of the clitoris situated at right angles to the long axis of the oval, and the clitoral bend leaving the tip of the clitoris pointed either outward or downward, depending on individual variation. Between the pubic bone and the clitoris is a layer of fat and muscle, a little cushion for it.

Men also have a symphysis or pubic bone. Theirs is above the root of their penis, and it is also covered with a layer of muscle and fat, giving it padding.

In intercourse, if the partners are well adjusted in terms of size and posture, the woman will position herself so that her clitoris is placed between her symphysis and her partner's. This is called "clitoris seizure." Then, at the end of each inward stroke he makes, she will give a little downward and outward roll of the pelvis which presses her clitoris rather firmly between the two bones and rubs it upward. This is called "clitoral excursion."

The effect of clitoral seizure and excursion is to move the clitoris downward as the penis enters -- and upward (under pressure and friction) at the end of the penile stroke. Thus, with each stroke of the penis, the glans of the clitoris is rubbed along her partner's padded pubic bone and the shaft of the clitoris is given a downward and then an upward tug. The upward friction-stroke of the clitoris -- caused by the downward pelvic roll she makes at the end of the inward stroke of his penis -- is the more pleasurable of the two directions.

The reach of the clitoral stroke can vary from half an inch to an inch and a half, depending on the size of the clitoris, how much it projects, how curved it is, and how deft the woman is at moving her pelvis.

If the woman crouches on top of the man and he makes no thrusts with his hips at all, the woman can control the degree of clitoral pressure and movement to suit herself perfectly, and can teach the man how much pressure and movement she likes.

Any woman who does this will most definitely experience clitoral stimulation during intercourse. A woman in a normal state of arousal well used to practicing clitoral seizure and excursion can achieve orgasm through intercourse with the same alacrity she could through masturbation, should she want to. She can also learn to control her movements to prolong intercourse a very long time, especially if her partner is cooperative.

By moving her buttocks outward and reducing the clitoral seizure, she can keep from coming too soon while her partner continues to stroke in and out.

Should she wish to slow him down while speeding herself up, she can indicate (through whatever form of communication the couple uses) that he should shorten his strokes or be still for a while. The lessened penile friction of a two-inch stroke will keep him from premature ejaculation, while still allowing her to experience a full inch-and-a-half clitoral excursion stroke, bringing her closer to orgasm.

If she wants true control, she can get on top of the man or they can lay side-by-side with her legs around him. These positions will allow her the fullest range of movement and amply compensate for the shorter length of her "tool."

With practice, full clitoral stimulation during vaginal intercourse and gently timed mutual orgasm will result.

I speak as one who knows.
