A woman's body size and frame, in my experience, are completely unrelated to the size of their vagina. Of the women I've been with, the larger framed ones have been a much tighter fit. This may fall under the heading of "Too Much Information", but one of the girls I dated before I met my wife was very nervous about sex, despite the fact that she "talked a good game". With her, vaginal sex was much tighter than anal sex, to the point of discomfort because she just couldn't relax. I guess this means that
Attitude was right about "frame of mind" affecting a womans reaction to penis size.
BTW,
BettyAnnMBSC, there is a guy on Swappernet who advertises a 9 1/2" cock and he has pictures to prove it. It's not 10", but who's going to quibble over half an inch.
