Message: Further questions about average vaginal widths

From: Amra_2003 Sent: 11 Oct. 2005 Message 1 of 15

I was reading the thread: "Who has reached 4" or larger" and found some interesting info there. The woman posting said she was 5' 4", and some discussion was made as to average pelvis size,etc. My wife is a bit over 5' 11", we used to fist pretty often, and she would actually enjoy serious "fistfuck", by that I mean not 'unmaking' a fist once I had it inside of her. Anyway, I am just wondering if average pelvis size is proportional to a womans height, etc. If a 5'4" woman can take 4", I wonder what should be physically possible for a woman 5'11", and to extrapolate that, what about those serious amazon type women that are like 6'3". Does the pelvis width or the distance between the bones increase proportionally?

Thanks!
Michael

There are two parameters of large pelvic size. Pelvic size depends naturally on proportional (relative) size. But even more important for extreme cases, it depends on a poorly understood condition called "Justo Major Pelvis", where every dimension of the pelvis is 1.5 or more times average (for her height). This is a rare factor of about 1:1000 or less and it seems to depend some degree on heredity, as it is not a random finding and maternal relatives are usually involved.

Did your wife's mother appear to have a wide, deep, and tall pelvis?

your wife's mother appear to have a wide, deep, and tall pelvis? Not noticably so.
Her, her grandmother, mother, and her sister are all 'amazons'. Her mother is 6 feet tall, her grandmother was like 6' 1", and her sister is 6'0", and my wife is maybe 1/2" less. But I would say that proportionally, my wives pelvis looks normal. Just scaled up, overall...lol.

Congratulations on having a large wife who likes fisting.

Your information means that the scale increase in size would be more than small ladies (Peyton, BJ etc.) who approach a maximum of 4.5" width with very very extreme stretching.

The Justo Major Pelvis factor that Jimm mentioned which increases size the most would not be involved. And with the most extreme stretching possible your wife would be about 13.3 cm across.

Remember to only advance to what is comfortable for her as she is probably no Peyton.

Height naturally becomes more of a factor if the same woman has a Pelvis is larger proportionally. There was once a giantess named Anna Swan who did not have a Justo Major Pelvis, but did have a large pelvis and she gave vaginal birth to an infant with a head 19 inches around. That same infant's shoulders measured 12 inches across and some doctors suggested that her maximum vaginal stretch during the birth was about 2/3 of that width (as the shoulder width compresses some during birth). Unlike smaller babies, very large babies always require a vaginal stretch size much greater than the infant's head circumference due to very big shoulders.

Without going to extremes here, every girl can, with a bit of practice, comfortably stretch to a diameter of 8 cm / 3 1/8 inch or a circumference of 25 cm / 10 inches.

Anything over that can be accomplished only with a lot of patience, dedication and practice.

During birth, due to the moulding of the infant's skull boneplates, the birth canal stretches to an average diameter of 9.5 cm / 3 3/4 inches or a circumference of 30 cm / 11 3/4 inches. But that is under the influence of a lot of hormones that induce stretching as well as natural muscle relaxants and painkillers that the female produces herself just before and during birth. Obviously she doesn't produce these same substances during sex-play.

Your wife has potential . Post anything you can.

Once had the short video of BJ inserting a 4.5 inch wide 2 liter bottle inside her vagina several inches deep, over and over.

Does anyone here have that video? If so, put it in the member's videos.

With your wife's larger size the ratio would make a 3 liter bottle insertion easier for her than BJ.

However, don't expect a lot, as BJ pushes her abilities to the limit. From the description of the Swan Giantess, if she had a Justo Major Pelvis just an average size vaginal stretch for her would more than satisfy my fantasy.

Good question, I was wondering the same thing, but about my wife who is 5'6". We have been fisting for years now. I never try to push her too far, but we have fun. You said your wife enjoys a serious " fistfuck" every now and then. My wife also enjoys this every now and then. I also use large toys to open her up. The largest being 11" around, so my question is this.

What is the max she could stretch if a closed fist or 11" dildo does not seem to bother her too much? Her pin bones are around 8" apart.

Let me say that no members on this Group have reported finding such a huge pin bone width before. I certainly hope it is correct, but want you to retest her by doing this:

Lying on her back on a bed, with both her legs drawn up toward her chest, take your right hand and make a fist (your fingers closed around your thumb). Now press firmly inward with you closed right fist over her anus area, and then press to her right until you feel the resistance of her right pin bone against the little finger side of your right hand. Usually the anus will still be under (not to the left side of) your right hand when you do this. This indicates the pinbone width from her right pinbone (which your fist is pressing firmly against) over to her left pin bone is less than two fists width. Now that you know where the right pinbone is, you may add bent fingers from the left hand to see if her width is more that one fist. Often a fist plus one or two fingers will fit between the pinbones when firm pressure is applied in and to both sides where the width between the pinbones is felt..

When you do this, with your right side of your right fist firmly against her right pinbone and you can see that her anus is showing to the left of your right fist, then your previous measure of 8 inches width is possibly correct. Then try both fists between her pinbones . It is extremely unusual if you can get two fists or two fists seperated from each other between a huge huge pinbone width. In any event measure the fist plus fingers (or in the extreme event of two or more fists) distance accurately by moving the fists plus fingers, or even two + fists, over a 12 inch ruler to get the exact measure between her pinbones and let us know.

This is a simple painless test and will let you know for sure.

Whatever your findings do not expect her to vaginally stretch more than about a half inch less than her pinbone width measurement, as few will enjoy stretching more than that far, even with practice.

Best wishes.

WOW! An 8" pinbone width. How erotic!

My head has a "cephalic index" of 0.8 Which means that front to back maximum head distance divided by side to side maximum head width is 0.8 In my case the side to side (like pinbone width) is 5.7 inches maximum width and maximum front to back distance is 7.125 inches.

In your wife's case her bone opening width of 8" minus my maximum head width or 5.7 inches would leave her a whopping 2.3 inches of extra stretch room and still alllow my head to enter such a huge vagina easily. That stimulates my "heading" fantasy, as I only enjoy what is easy to do, safe, comfortable, and fun for both parties. Thanks for the post and put up a picture anytime!

From: Partialn Sent: 16 Oct. 2005 Message 10 of 15

Sorry, I meant to say in my description above that the cephalic head index is (side to side divided by front to back) which like mine is usually about 0.8 : 1= 0.8 and is the same reason that the ratio for pelvic bone openings ( the side to side pelvic opening divided by front to back opening) is similar and makes it easier for birth of these oval heads.

Sorry for the mistake her hip bones are 8" on the part of her hips she sits on. I will try to get the right size of her pin bones next time we play around.

From: Jimm Sent: 4 Nov. 2005 Message 12 of 15

Thanks! Knew your measure was probably not "between" her pinbones. Any woman who had a 8" would look very different and would not only be almost twice as wide as average women across her hips but would have a very very tall pelvis. You might have to observe a million women to see just one like that. But who knows you may see one tomorrow LOL

Whenever you measure let us know. About 4.5 inches is average.

From: Partialn Sent: 4 Nov. 2005 Message 13 of 15

Read in the paper today that the Waist to Hip Index was a better predictor of heart disease than the BMI Index.

A woman with a 8" pinbone distance compared to the 4.5" average would be about 1.8 times average pelvic size, and if not fat, would have her hips about twice as wide as her waist. She would have about a 0.5 waist to hip index and be very unlikely to have heart disease.

I have seen a couple of women over the years with hips twice as wide as their waist, but they may not have had the very tall pelvis. To be a true Justo Major their pelvis would have to be very tall as well as wide.

Well I think my wife is 4" to 4.5" so what can I expect her maximum to be without pain?

From: Jimm Sent: 9 Nov. 2005 Message 15 of 15

You mention a 11" around toy (3.5 inches across) that your wife has used. As she is probably 4.5 inches bone width (between the pinbones) with a 1 inch clearance between her pelvic bone opening and her vagina now, she might get a little larger.

A clearance of 2/3 inch between her vagina and her bone maximum width might still be comfortable, but don't expect a lot more side to side size as even that would only be third inch wider than what she takes now.

Everybody is different, so who knows, she might stretch near her very maximum bone opening without much discomfort. Just try to stay with whatever is comfortable for her.
