Instrument for Measuring the Vagina

I once saw in a medfet porn video a doctor using a plastic device with markings to measure the depth of a woman's vagina. He had her get into various positions and would then insert this instrument to measure her. I believe it was white and clear plastic. Anyone know what this is and where to purchase one?

It sounds like a Welch Allyn Sigmoidoscope #53130.

Available on eBay, and at other outlets.

I'm looking for something similar myself.. the ones I have seen don't have a separate handle like the sigmoidoscope, but are rather shaped much like a vibrator - either tapered or the same girth over the whole length, with ruler-like markings. I found such a thing listed under the brand "Inch Perfect" (was basically a white vibrator with ruler markings), but it appears to be discontinued.

Any suggestions on what this device would be called or where I might find one ?

Why are you making this complicated?

Get a double dong like this

take a ruler and mark of inches on the dildo and presto, a depth gauge.

Sounds a tad difficult given it's highly elastic.

It isn't difficult at all.

You will just get a range of measurements.

Just curious- Once you have such information, what do you do with it?

Some of the info probably goes into comparisons with other women category, others into the "mine is bigger or smaller than yours" file and still others is to make a goal to increase it.

That only compounds the question, because how many women will allow one person to measure them? If the answer is one (significant other) the result is essentially useless.

If one is satisfied with the results from a group of one, because the goal is to increase that measurement, what technique would be used? My imagination says it would have to be something dildo-like that pushes inward, against the cervix, which is making me say ouch already.

An interesting topic. I have to wonder (hope) if there is a device not just to measure the depth (assuming labia to cervix here) but rather tightness. Say, an instrument that when properly inserted would accurately and objectively measure how snug a woman's resting vaginal tunnel was in comparison to others. Probably in units of pressure, but normalized for texture / friction. Naturally we would want to compare across physical stature, age, ethnicity, and geographic zones, while controlling for number of sexual partners and frequency of coitus, or coitus-like activities (i.e. dildos, Sybian work-outs, fisting etc). This could be an epic graduate level study project.

Agasmic- There is just such a device. It's called a penis.

I wondered which horndog would answer it this way, and happily I see it was you @Buttwoman.

Well done!

Butt (see how I did that) we would need 'solid' numbers - so perhaps a pressure transducer attached to a penis would do the trick? But, that would be a lot of field research for one volunteer. It could take me a while, although I wouldn't mind starting in Canada...

Any way you look at it, the results are useless unless you plan to dump the woman for someone with different measurements.

What difference do the measurements make? They are what they are and men aren't going to change to another woman anyway for that reason. The men are probably thrilled the woman will let them measure them in the first place, which makes the woman a "keeper".

The dildo idea sounds very improvised - I was personally going for the visual of the ruler looking thing. As with many others, I'm particular about having the specific instrument I desire, versus improvising from something else. That said, I may end up resorting to a plastic vibrator and somehow etching marks onto the shaft (permanent markers or other such things may not be wise for such a sensitive area). Unless there's a better way to accomplish this ?

As far as what to do with the measurements or why bother, that's because my wife and I are both rather curious about how her depth changes between different positions (sitting, standing, laying down, etc) - it's not for comparison against other women.

Really we both just saw it in a video once or twice and thought it would be a kinda hot/kinda fun toy to play with.

This discussion has turned strange. Who cares about depth as long as both are satisfied. Are we now going to have a depth contest?

Course

Squatting and doggie positions will noticeably shorten the vagina.

?

At 76, my 'ol fellar' doesn't reliably perform any more and my previous partner wanted sex and 'it' wouldn't stand up. SO, I wore a strappon and she said that it was a bit too long for her and "don't push it in so far". A happy and satisfied lady. regards, irrigator333

Thinking back on all the reading I had done and if my memory serves me the vagina changes and slowly adjusts to what is being inserted. Different size penis's both length and girth, and the cavity will adjust, and so I am left with the question why. If the vaginal cavity is so elastic, then what good will an measurement be. Is there some scientific learning to be involved? Only thing I could see is in a non aroused state it could be one size and once aroused with time it will increase to some degree depending on what is inserted. If this is to be incorporated into some sort of kinky play with a purpose, then okay, it works for you.
