admittedly I only heard that particular statistic once and it was in a female comic's standup routine, so I don't know how accurate it is.
This site Most capacious human vagina isn't much help but does have an interesting anecdote.
Vagina - Wikipedia, the free encyclopedia @ Wikipedia it lists the vagina's average length in a non-aroused state (4 inches long and 1 inch in diameter). But gives no figures for a vagina's length in a state of arousal.
I would assume that, like men, women have various lengths and states of arousal. Unlike men, it would be much more difficult to measure the inches.
