FMH,
Let me answer your question first. I'm completely childless and wish to remain so, however I do love other people's children!
What I think you are trying to tactfully ask is (in a white-trashy backwoods redneck accent) "Hey all you providers with tight pussies out there, please raise your hand."
Yes this is absolutely vulgar, but I'm attempting to stay light-hearted on a touchy subject, so please understand I mean no offense.
Reading through medical journals I've condensed into medical language basically the research I've found on this topic.
- A woman's vaginal canal does change directly after giving birth.
- A woman's vaginal canal almost always goes back to the same size (although there is variance - some get smaller in width, some larger)
- Kegel exercises are almost always successful re-toning the "pelvic floor muscles", the ones that "make it feel tight" (again with the vulgar language - sorry)
- A woman's vaginal canal changes width throughout its length -
- the smallest in width being at the opening (the introitus - the average width 1.03 inches); and the largest at the deepest into the body (proximal end of the vagina - closest to the uterus - average width 1.28 inches)
- In the same woman, measured at different times of the month - the width of her vagina can and does change by several millimeters (I was surprised to learn this)
- Race has not been scientifically shown to be a factor in assessing the size/width/length of vaginal dimensions
So I guess the medical evidence is steering us back to the Kegel Exercises.
HOWEVER (quite interestingly enough) in my research on this topic I found some interesting items for MEN on Kegel Exercises.
From Wikipedia:
Benefits for men
Though most commonly used by women, men can also use Kegel exercises. Kegel exercises are employed to strengthen the pubococcygeal muscle and other muscles of the pelvic diaphragm. Kegels can help men achieve stronger erections and gain greater control over ejaculation. The objective of this may be similar to that of the exercise in women with weakened pelvic floor: to increase bladder and bowel control and sexual function.
Sexual function
Kegel workouts can provide men with stronger erections. Research published in 2005 issue of BJU International, have shown that pelvic floor exercises could help restore erectile function in men with erectile dysfunction. (Basically, us ladies won't have to try to wake the dead - )
It is also possible that strengthening the pelvic floor may allow some men to achieve a form of orgasm without allowing ejaculation, and thereby perhaps reach multiple "climaxes" during sexual activity.
So while, yes, this thread is about women and how small or large they are - it seems that the gentleman's physiology can be enhanced, just like a woman's in order for both parties to achieve maximum pleasure.
