[/indent][/indent][/indent][/indent]Let me just throw this in; I'm a midwife and I've delivered maybe 100 babies in the last 13 years. In each case I have to examine the mom to check the cervix.
I'm about 5'2" and my hands are not that big, but there has never been a woman that I've not been able to feel the cervix.
I might have to push, use some pressure, but I can't say that I've noticed much difference in a woman 5' and 100lbs to 6' 200lbs and those in-between.
Personally, my husband is about 8" in length and there is no way he has ever gotten more than 'maybe' 5 inches in me. Some positions are just not comfortable. Girth- last time we actually measured was 16 years ago, then it was close to 6". He would have been 33 at that time. His erections are not as hard as they were then, so girth may be less now.
We could not have intercourse the first time we tried. It might have been the 5th or 6th time he was able to get in somewhat, but he had to just stop there because it felt as though my urethra was being painfully pulled apart.
We were engaged by the time we first had sex and I was living in his apt., so I was not like we were kids in the back seat trying to have sex. Overall I was comfortable (emotionally and physically) and lubricated, but size was the problem.
It took a few weeks to be able to have intercourse and my vaginal tissue relaxed. If we go a few weeks without having sex, I am snug again.
But even if a women was a virgin, then becomes sexually active for 5 years and then for some reason does not have vaginal sex for a year or two, the vaginal tissue will shrink somewhat.
I suppose the bottom line is: how much is too much? There are men on this board who are not having sex (or less sex) because their wife finds intercourse painful do to hubby's girth.
I'm not sure that a larger woman is going to have a larger vagina. The average vagina is between 3-6 inches and I'd think most are 4& 1/2.
Genetics might affect size, height might, but weight is not going to affect the size of the vagina.
Give this a lot of thought, I don't think you can size down if you change you mind!
