Really the only thing I have to contribute is this--the vagina is incredibly resilient. One night of violent--even tearing--sex isn't going to "ruin" a pussy. Given any time and attention at all, any pussy can be whipped (no pun intended) back into tight shape. The kind of "wrecking" it would take to permanently impair a vagina would involve, oh, a machete? When you think that women can bear children, incur severe perineal tearing, and yet bounce back, a virgin taking the mythic 12 inches in the context of a fantasy tale doesn't necessarily indicate a vagina no longer fit for use.
