The Vagina

Some facts you may not know about the human Vagina:

  • The pleasurable nerves are only located on the outer one third of the vagina – any deeper and she’s not feeling it anyway.
  • The average vagina is only three to four inches deep.
  • Average vaginal width is a little over an inch for most women
  • Many women report that men whose penises are too big actually feel uncomfortable during intercourse, even painful.
  • Most of the nerve endings that cause females pleasure – eight thousand of them to be precise – are not even inside the vagina. They’re in the clitoris, which is where you want to be spending more of your attention.
  • The G-Spot is only about 2-3″ inches inside the vagina on the top (below the bladder) so size has nothing to do with stimulating it. Besides, research shows only a small percentage of women can have vaginal orgasms, but all women can have earth-shattering clitoral orgasms.
  • The idea the vagina gets longer and wider when a woman is aroused is a myth. It has never been proven scientifically that it occurs. There are some changes to the walls of the vagina when a premenopausal woman is aroused, but the vagina does not get wider or longer.


A 1996 study: “The shape and dimensions of the human vagina as seen in three-dimensional vinyl polysiloxane casts”. Gynecologic and obstetric investigation 42 (3): 178–182, used vinyl polysiloxane castings taken from the vaginas of 39 Caucasian women, found the following ranges of dimensions:

  • lengths (measured using rods): 6.86 to 14.81 cm (2.7 to 5.83 inches);
  • widths: 4.8 to 6.3 cm (1.88 to 2.48 inches);
  • vaginal entrance diameters: 2.39 to 6.45 cm (0.94 to 2.53 inches)


Research published in 2006 (“Baseline dimensions (non-aroused) of the human vagina”. Human Reproduction 21 (6): 1618–1622.), gave the following mean dimensions, based on MRI scans of 28 women:

  • Mean length from cervix to vaginal openings: 6.27 cm (2.46″).
  • Mean width:
    at the proximal vagina: 3.25 cm (1.27″);
    at the pelvic diaphragm: 2.78 cm (1.09″);
    at the vaginal entrance: 2.62 cm (1.03″)


Sexually pleasuring a female is not as hard as you think, and penis size doesn’t have to be a factor (unless you are in the extreme size ranges). There are many sexual techniques that can be used, other than intercourse, that can give a female an intense pleasurable experience.


The Most Important Thing To Know About Vaginal Sex.

Only 25 percent of women are consistently orgasmic during vaginal intercourse.

This bears repeating: Only one-quarter of women reliably experience orgasm during intercourse-no matter how long it lasts, no matter what size the man’s penis, and no matter how the woman feels about the man or the relationship.

This statistic comes not from just one study, but from a comprehensive analysis of 33 studies over the past 80 years by Elisabeth Lloyd in her fascinating book The Case of the Female Orgasm (Harvard University Press).

Rounding things out: About half of women sometimes have orgasms during intercourse. About 20 percent seldom or ever have orgasms during intercourse. And about 5 percent never have orgasms, period.

In other words, intercourse is not the key to most women’s sexual satisfaction.

Now I’m not knocking intercourse. It’s central to reproductive sex. If it’s well lubricated and men don’t plunge in before women feel ready, it can be great fun. And it makes many lovers feel deeply connected. But contrary to what many men and women believe-and see endlessly in porn-intercourse is not the essence of lovemaking.

This statistic has several important implications:

* It’s perfectly normal for women not to have orgasms during intercourse. Most women need direct clitoral stimulation to experience orgasm. They don’t get it during intercourse because the clitoris is located outside the vagina and a few inches above it under the top junction of the vaginal lips. Intercourse simply does not provide enough direct clitoral stimulation to allow most women to become aroused enough to have orgasms. “Intercourse is okay,” says New York City sex educator Betty Dodson, Ph.D. “But I much prefer a talented tongue on my clitoris.”

* Penis size doesn’t matter to most women’s sexual satisfaction. If only 25 percent of women are consistently orgasmic during intercourse, then for most women, penis size doesn’t matter. The fact is, any size penis can provide great pleasure to the man it’s attached to. But they key to most women’s erotic pleasure comes not from the penis and intercourse, but from direct clitoral stimulation, using the fingers, palm, tongue, or sex toys.

* Lasting a long time during intercourse may not matter as much as many (most?) men think it does. Why do men want to last all night? In part because they believe it’s more pleasurable for women. Many women do, indeed, enjoy extended intercourse, whether or not they experience orgasm. But only one-quarter are consistently orgasmic during it no matter how long the man lasts. (For men who want to learn better ejaculatory control, a chapter in my book, Great Sex: A Man’s Guide to the Secrets of Whole-Body Sensuality, teaches it.)

* Finally, because so few women are consistently orgasmic during intercourse, it’s fine to have sex without intercourse. This is especially true for couples over 40. With age, men’s erection capacity declines, and menopausal changes often make intercourse uncomfortable for women, even with a lubricant. Many older couples decide they prefer sex without intercourse. Younger lovers might also consider this erotic alternative.


Vagina Myth – It gets longer and wider when a woman is aroused.

There is a myth in society that womens vaginas get bigger when aroused compared to non-aroused. The slang term often used for this is “a wide-on”.

However, an MRI based study done in 2004 (MRI of female genital and pelvic organs during sexual arousal) showed no differences in length nor width from non-aroused to aroused in both premenopausal and menopausal women. The study said:

Measurements of vaginal width, wall thickness and canal length did not change with arousal in both pre- and post-menopausal groups. Vaginal wall enhancement increased with arousal only in pre-menopausal subjects. In the premenopausal subjects there were numerous infoldings of the vaginal mucosa (rugae), creating an irregular surface. Post-menopausal subjects did not have distinguishable mucosal rugae or clearly separate layers of the vagina, presumably due to atrophy and flattening of the vaginal walls (Figure 4). Thus, the lack of enhancement in the post-menopausal group was attributed to smaller tissue volume. There were no discernable changes in the shape, position, or axis of the vagina during the aroused state.

The study does suggest there are changes to the mucosal lining of the vagina during arousal, but they don’t get longer or wider compared to non-aroused state.

And Now – A word From The Women:

    Great stuff. ….
    I was free of guilt when I ended relationships with nasty women who want just a big dick and try to make an avg endowed guy feel insecure regardless on how great of a guy we are.

    Your site is superb and self acceptance is the key to happier times. ….

    This is a very good site. I have often felt my penis was neither wide or long enough to satisfy women and have felt inadequate, depressed, bitter and angry and the way I feel about it does affect my relationships, current one included. I realise I have to accept it but I find it so hard (even with hypnotherapy). I am determined to lose weight, it would be nice to see more of it in the mirror, but depression makes it hard to stick to a routine. My confidence and self esteem is low as a result of my penis size and being overweight (3 stone). I can’t change my penis (frustratingly) but I can try and get an attractive body.
    Good sex ed on the Vagina as well.

      @Kamikazewomble, (from a woman’s perspective) – In the hopes of helping you feel better about yourself, I’ve had two lovers (consecutively, not concurrently!) and the first guy was a fitness freak, a good build and a lousy lover and the second was vastly overweight (about 4.5 stone) and was a great lover.

      By all means, get your weight under control for your health’s sake but try not to see it as a barrier to being a good lover. It’s not, I can assure you.

    Very helpful and well written,

    unlike some other sources that suggest if you don’t shove a Chernobyl waste missile into your partner you’ll never achieve sexual pleasure,,,this isn’t how it works.

  4. Vincent Pitts

    Yes. The vaginal length is 2.5 to 4″. The deeper a man goes won’t prove anything accept his own because she has no sensitive nerves that deep. Outer/inner wall of the virgins is most sensitive and a man with 3″ can please her well and using all his tools of trade (Hands, tounge, etc). Nice report for the aggressive man and I want it bigger woman. Thanks. Love health

    That’s a perfect lecturing. Ladies frightening guys of small dick have come to know and guys frightening ladies with their big dicks has been alerted on line. Superb!!
