A little persons sexual organs are slightly smaller than the average size persons. The length of the birth canal of a woman is proportionate to her height. For a woman of average height 54, the birth canal can be 811 inches before hitting the opening of the uterus. This would not be possible for a little person as the organs in the body are closer together than an average persons. Therefore it is safe to assume that the birth canal is a couple of inches shorter.This doesnt include the WIDTH of the vaginal opening. The vagina is a miraculous muscle as it is capable of stretching as much as 25 times its original circumference. Therefore, a little person would have virtually no problems having sex with a man with a normal to aboveaverage sized penis. There is a limit on the penile length, however, as a penis trying to poke through the opening of the uterus would be painful, depending on how high or low your threshold of pain is.The bottom line is, yes a little persons vagina is shorter in length and width, but the organs are fully developed, so having sex would not destroy or damage the ability to have babies as would be the case if a teenager or preteenager of the same size was sexually active.The real question is how do so many people come across a yahoo answer page about the size of midget vaginas!?
