I would think a woman's vagina could take a pretty big penis, think about it women have children everyday look at the size of the children the come out of them.In conclusion it is physically impossible for an all natural penis to stretch the vaginal muscles to there full capacity.
Vaginas can be different lengths due to genetics. Anything over six inches has the potential to hit the cervix and cause pain.
Depends on the girl.
Depends on how big the penis is. The average vagina is 4-6 inches deep and 7-9 inches when aroused. not much more than 8in, because then it could rip or damage her insides The vagina can stretch for most size penises. The average is 6'' long. It depends On the woman if her vagina is small she can't take a big penis so you have to c how big her vagina is It really varies from girl to girl, but take it easy if she says sex is painful. AnswerTypically the female vagina is 6-7 inches deep. therefore only 6-7 inches is allowed for penetration. Type your answer here... me being a female , i think it should be a normal size... from 5 inches to 6 inches... my bf have 5.5 but strong fully errected hard...it must hit the clit with force. its useless if itsbig but no errection. when aroused a vagina is usually about 6 inches deep
