PUBLIC SERVICE ANNOUNCEMENT: THE DEPTH OF A WOMANS VAGINA DOES NOT CHANGE DRAMATICALLY WITH AROUSAL.
Hey, femanon here. I see posts all the time about how women prefer large penises and how apparently, 8 or 9 inches is ideal. Occasionally a voice of reason points out that anything above 7 inches is likely to be painful for a woman - absolutely true - but it's still disregarded and ya'll insist that 9 inches is where it's at.
There are a lot of sources over how deep the average vagina is, with most saying 3-4 inches, although I'd wager it's closer to 5. The vaginal walls are made of muscle with accordion like folds, and at the end of the vagina is the cervix.
During sex the vagina can expand to accommodate a penis but 80-90% of this is WIDTH. The muscular walls stretch UP (towards the navel) DOWN (towards the rectum) LEFT and RIGHT to conform to CIRCUMFERENCE of the object, appendage, etc.
In order for a vagina to change in DEPTH the cervix has to ascend, this can give you an extra inch, two at most. Whether or not this happens is mainly psychological, like the presence and volume of lubrication or ejaculate.
A highly aroused woman will probably have a vagina with a depth of 6-7 inches, with a rare few having an 8+ inch depth. This allows guys who are 6 inches to go balls deep and exert mild to moderate pressure on the cervix, but 7 inches or higher is really pushing it.
"BUT WOMEN GIVE BIRTH TO BABIES"
Yes, yes we do. During birth as the infant passes through the birth canal - notice the use of 'birth canal' which refers to entirety of the reproductive organs the baby must pass through, not 'vaginal canal' - part of the baby is still INSIDE THE UTERUS. The baby doesn't exit the cervix and then just fucking sit there in the vagina.
Some of you seem to think that if a woman is aroused, the vagina magically becomes 10+ inches or of indefinite depth, this is impossible as it would require the movement of other internal organs. You guys are retarded.
