That anyone with more than 6" will not be allowed intercourse as her vagina was very short and it hurt her to have intercourse with anyone over that size.

The ironic thing is that this provider was very, very large sized in every other respect.

There have been times when a woman will tell me that I'm too long and she finds it uncomfortable because I'm hitting the cervical opening.  One woman has told me that I rearranged her furniture (trying to be cute.  lol)  Occasionally I have had a woman try to limit my depth using her legs.

Ironically, I'm very attracted to petite ladies and this has been a problem with some of them.  I have not had any complaints from the ladies of larger stature.

It's been an issue in a small percentage of of my experiences but it's upsetting to me when it happens.  I should mention that I am a considerate and caring man.  I'm talking strictly about a size issue, not a forceful thrust issue.

I may have answered my own question but just asking for confirmation.  Do petite women tend to have shorter vaginal anatomy?  I would say yes, based on my experiences and common sense.

depending not her arousal & her own progress toward climax (hers).  I had a rear hands & more on education from a Planned Parenthood RN who was my GF at one time.  Just for the record, I was just average sized but she would have tremendous climaxes if I rubbed her cervix.  Note that I did not pound her there.

It's not just the length of your member but a combination of position, angle, arousal.

“Love is very deep. Sex only has to go a couple of inches.”

I think this is true (position and arousal)

I also noticed if I'm close to my menstrual cycle(and/or after I ovulate) my cervix is low. I find intercourse uncomfortable unless I'm really aroused. If I'm really aroused I can have a tremendous orgasm

Yes, there are variations in depth among women, the same as there are variations in length among men. I don't know how much of a role a woman's size plays in determining her depth, but it seems logical to me that a woman of short stature (petite in height, regardless of weight) would have a shorter vaginal canal. After all, at 5'1", my torso is shorter than a woman of 5'6", so why wouldn't I be somewhat more compact than a taller woman. Again, that is just my theory, I have no idea if there is any validity to it.

Speaking as a lady who is all of 5'1" though, I can tell you that any man who is around 6" or longer will bottom out and hit my cervix. Its why I say size really doesn't matter, and why I prefer men of rather shorter endowment.

But that isn't quite all there is too it either. As the link LG provided indicates, and SKB reiterates, arousal plays a huge role. It can be excruciatingly painful if a partner fully penetrates me immediately. I'm simply not aroused enough, and the sensation of having my cervix hit is extremely unpleasant. However, when I am fully aroused, it is the very sensation of hitting my cervix that will push me over the edge to orgasm. Go figure huh? I'm sure I send some very mixed messages when I say "not so deep!" at first, and then turn around and tell him to go deeper while grabbing his hips and pulling him in.

So, the take home message is take your time, penetrate slowly and find her comfort zone. Let her arousal build and be the guide to know when to go deeper.
