Just how deep is a woman's vagina?

Dr David Mconachy states
The ladies vagina depth can vary dramatically, however the average depth is around 6inches however the largest recorded depth of a vagina was recorded in London, 1916 and the depth recorded was 17.5inches. This is very deep.
Hope this helps, Dr D Mconachy, gynecologist, UK

There's no one answer to that. Just like males have different penis sizes, women have different lengths in the vaginal canal. It usually depends on how tall or short the woman is, her body chemistry, etc. It is usually deep enough to accomodate the length of a full-grown male penis, on average 4.5-5 inches. Some are more 'shallow', some are deeper. It will always vary from person to person but it usually deep enough to accept the length of an average sized penis before entering the cervix.

It's interesting to note, also, that the majority of sensation a woman feels is localized in the first three inches of the vagina.

Mine's at least this deep.

How the Fk can you record a 17.5 inch I smell BS...I'm 5'10 and 17.5 inches is the distance from my penis to above my nipples. So either that woman's vagina went from between her legs all the way past her heart (impossible) or she was 8-10 feet tall (also impossible).

It depends on the woman, but the average is 5 to 9 inches deep when aroused. Some women are deeper than this, some not.

The woman's vagina can be averaged 5-7 inches long when aroused. Of course there are women with very long canals and some with very short ones. But the above numbers is the average.

depends on the person like penis size

Vaginas vary greatly in depth, as, of course, does every part of the body.

The most relevant question is whether it's going to be deep enough for a particular guy's penis to go in and be used enthusiastically without hitting the cervix and thus causing great pain and possible bleeding.

In general terms, assuming that neither partner's genitals differ too widely from the norm, they're like to fit together quite well if the woman is just a couple of inches shorter in height than the man.

You don't often see it nowadays (gets operated on long before that stage) but you used to see total prolapses of the uterus, where it pushed right down and turned the vagina entirely outside in (procidentia) -- certainly showed what that particular vagina had been like as far as depth was concerned. A large proportion of our great great grandmothers spent the last decades of their lives with a protuberance bearing a totally-remarkable resemblance to their husband's penis

The length or depth of the vagina seems to vary quite
a bit. My Gynecologist says that mine is about 7 1/2"
I have always had trouble accomodating my partner.
My Doctor has sent me to a specialist, who say's he
can lenghten my vagina between 2 1/2 to 3 1/2".
I'm wondering if there are other women that have
had this done.
I would like to inhance the penitration for us
both if I can.
