How deep is cervix on average

Hi, I wanted to know how deep is end of vagina for average woman? I read somewhere that majority in aroused state is between 5 - 7 inches, and most of them are about 6 inches deep when fully aroused which would make sense because most man also have average 6 inches in length, however that would mean for example if someone have 6.5 inch NBPEL and 7.0 BPEL he would hit cervix for a lot of woman and couldn’t go balls deep always. So other question is how much really you loose do to position, because I guess you don’t enter always 100% of your size, and I am talking about woman who are in shape and not overweight, because than you would loose even more. Another thing could be that cervix after some bumping goes up even higher for another additional 0.5 - 1 inch but not much more. What are your thoughts on this subject?

You also have to remember that your balls take up some of your length. Assuming you measure from the top, that half inch to an inch at the bottom is not really usable. In addition to the amount lost due to position you won’t be able to use at least an inch. Meaning around 7.5 NBPEL would be required to bottom out on most girls.

At least an inch due to positioning wouldn’t be able to use? Maybe for most overweight American girls. But generally I think it is more like half inch in missionary and doggy style position.

Read up on cul-de-sac. Basically when woman is aroused her cervix ascends and you can slide past it to the CDS (cul-de-sac). The stimulation of CDS can give a women another kind of orgasm the CDS orgasm. I estimate length needed to reach CDS - 7.5-8.25” BPEL for most woman.

That bottom length is useable from the correct angles.

Ok most likely around a half inch is lost, but in some positions it can be up to an inch and my girl is by no means overweight. You also have to remember that missionary is good for going deep an doggy somewhat.

Although like Dj said you can use that bottom length at the right angles, and occasionally in those positions I can bottom out. So I guess that puts the 5-7 inch estimate about right. 7.5 NBPEL would make it possible to bottom out almost any position probably.

I’m almost seven inches long and on a good day slightly over BPEL. I hit my wife’s cervix if I’m not careful.
