Question related to the length of the vagina

Actually two questions.

From what I have read/heard, the average length of the female vagina is 6 to 7 inches. At the end of it is the cervix of the uterus, that I assume is not penetrable.

  1. If the length of the vagina is 6 - 7 inches, and considering the use of the middle finger which is the longest at hardly 3 inches, how does a woman use one of those birth control devices e.g sponge, film etc where it is essential that the device sit snug against the cervix? How does she reach 6 - 7 inches deep in the vagina to be able to feel the cervix and make sure that the device is appropiately placed?

Supplementary question:

  1. Again, if the length of the vagina is as mentioned, how do men with penises longer than 7 inches penises(as witnessed in porn films) fit it into a woman’s vagina? Where do the extra inches get absorbed? Does the cervix have nerve endings of sensation? If the penis hits against the cervix, is the sensation for the woman painful or pleasurable?

My sources say that the vagina is only 3 to 4 inches long. Although that doesn’t explain where the other 2/3 of my penis goes.

I heard she asked you to give her 12 inches, and make it hurt, so you did her 4 times, and punched her in the face.

To the OP, I’ve been with women whom I could touch their cervex with my middle finger, but only if the index finger were inserted also. It’s a bit of a morale booster if you can “bottom out”, so to speak, so easliy. :smiley:

This doesn’t really address the OP, but it’s all I’ve got, and I had to share.

I don’t have any stats on the length of the vagina, but I can say that some of “where the rest of the penis goes” is, well, outside the vagina, against the fat of the labia (where, if the angle is right, it can stimulate the clitoris during stroking).

Personally, if I’m penetrated by anything long enough to “bottom out” and hit my cervix, well. . .if it just happens once, I’m likely to go “Hey, knock it off”, but if it happens repeatedly, I find it damned uncomfortable. YMMV.

The vagina expands during intercourse/arousal. You can Google some combination of “vagina expands length intercourse” for numerous cites.

According to a quick check of these cites, some women find penile contact with the cervix painful, others pleasurable. (My own experience as an owner of a cervix is, “It depends” – on position, depth of penetration, level of arousal, etc. And I can easily touch my cervix with a finger.)

That can get you alot of interesting results that don’t answer the question too.

Agreed, but by how much? Can a 4 inch vagina expand by 100% to 8 inches?

So, I guess, at 4 inches it is quite possible to be able to touch the cervix with the middle finger.

wisernow, while the SDMB may be great, there’s no subsitute for empirical research.
Get yourself to the nearest single’s bar!

From personal experience, the vagina does expand a little depending on arousal level. However, with someone who tops out at 10 inches (their phallus, that is) penetrates a woman with a 7 inch vagina, a good 2-3 inches may be blocked off by the distance between the hips and the vagina itself. Often enough, the vulva takes up most of this space, but most of the time, it’s an issue with the hips not being able to make full contact with the pelvic mound. (Note: when doing things “doggy style,” one does not have as many things impeding progress, and slamming into the cervix is a very real possibility.)

The cervix is an interesting area, as it has its own nerve endings, and can react to contact from a penis (or other phallic object) with varying degrees of pleasure or pain. If you hear “ouch!” when it happens, try not to hit the cervix again. :wink: :stuck_out_tongue:

Well the way I heard it the average vagina is 7" long, and the average penis when erect is 6" long. That is 1" of unused vagina in every female.
New York City has a population of 8 million people, assuming 50% of them are women that is 3333.33 feet of unused vagina.
In New York City alone there is over 63 miles of unused vagina! :eek: :smiley:

True…but if you multiply the size of the average schwanz by the average number of strokes during a good romp, the women of New York have been screwed to the moon and back six times each year.

Ok. So I made that up. Sue me.

Knock off the extraneous posts. If you have something to add that answers the OP, then do it.

Otherwise, start your own joke thread in MPSIMS.

This is hardly the thirst GQ thread I’ve read with joke posts. Why bring it up now?

I must agree.

For example, this:

is priceless coming from a poster called x-ray vision.

How can one let that pass without comment?

This is another thing I do not understand. If the cerix has nerve endings for the sensation of touch, why should it be painful for some and pleasurable for others? Why should the sensation be different for different people? Is there any other part of the body with similary individually varying characteristics? Off hand I can’t seem to think of any.

It is true that the intensity of a sensation maybe different for different people, for example what causes me agonizing pain may not cause pain with the same intensity to another person. But how can something be painful for one and just the reverse for another? If true, then what is the explanation? The only one I can see is that it has to be psychogical, in which case it would more appropriate to say that even though the sensation is that of pain, some people like it nevertheless.

You may have seen some illustrations by now. You seem to picture the vagina as a tunnel with a closed door at the end. Not every vagina is the same, but the cervix’s “door” is usually a rounded bump intruding from the ceiling of the tunnel. There’s a bit more tunnel beyond that, and the walls are stretchy. With a different angle, the penis can slip past the cervix, under it or to one side. Once you’ve gotten there, the two of you begin to find out just how stretchy she can be. That’s another thing that varies from one woman to another, so explore gently at first. She’ll let you know if it’s working.

What’s your preferred level of hot-pepper spiciness in food? Do you know anyone with a different preference? Are you ticklish? Everywhere, or only in certain places? Do you enjoy the refreshing feel of a brisk cold wind on your face, or are you the kind of person that can’t get enough of the hot weather?

hot peppers? pleasurable for some, painful for others.

playing with your butt-button, free-fall?

Nipples. Some people apparently like them being touched, others can’t stand it.

As a person who has had a hand in many vaginas (OB-GYN nurse), I think I can address your questions!

The vaginal walls are just as stretchy and flexible as the penis. The rugea (wrinkles) of the flacid penis is a fairly compatible (but not exact) example of the interior of the vagina. The vagina typically runs 4-7 inches from introitus to cervix.

The cervix is not located at the end of the tunnel- like a pipe with a donut at one end. The cervix is generally located at the top of the vaginal ‘tube’, and at the end of the tube is a pouch called the fornix. Picture here:

Being flexible, the length of the vagina can be slightly shortened and lengthend by body positioning with standing straight lengthening the vagina and bending/squatting shortening it. Also, the introitus or entry to the vagina is fairly squishy and flexible. The pelvic bones (ischeal tuberosities) are about one third to halfway up the vaginal vault and except for the pubis bone in front, this area is mostly soft tissue and easily compressed.
Fitting a sponge against the cervix just requires the sponge to be pushed in flat or folded. The sponge or diaphram has a concavity that allows it to “cup” the cervix and stay in place. The penis will slip past this obstruction in the same way it slips past the cervix.

The sponge has a band of material, a soft handle, that one can loop onto a finger to pull the sponge back out. The sponge is fairly bulky and difficult to miss with a finger sweep.

The diaphram is a little more difficult to remove and may take a couple of (or several) tries to get the technique down. The one finger techniques involved ‘hooking’ and edge and pulling. There has been many a woman appear at the OBGYN office to have diaphrams or tampons removed from the vagina.

Incidently, the position of the cervix increases the chance that sperm can get past it and on to the egg by keeping the sperm in and about the fornix and keeping the cervix “face down” and in contact with the sperm.

Others have addressed the cervix sensation question. Most women I know find direct pressure to the cervix unpleasant to some degree.
