A metric to determine if a woman is wifey material. A female that has had sex with a lot of men has high (and/or heavy) crotch mileage. The same way a used vehicle with a lots of mileage may have a lower blue book value; females with high (and/or heavy) crotch mileage are less desirable.
The chick I'm dating seems like wifey material, but I can't get over the fact that she's slept with 30+ guys, her crotch mileage is way too high for me.
