Cock mileage

[Mark Zuckerberg]

The unit of measure for how worn out a womans vagina is which takes into account such factors as the [cumulative] number of thrusts from penises into her vagina, the size of each penis, how often she uses a dildo, the size of the dildo, how many babies shes had, etc...
[Cock mileage] is the unit of measure for the comprehensive wear that has been imposed on a womans vagina and an indicator of how pleasurable sex with her will be.
Men with larger penises will usually be able to tolerate women with higher [cock mileage] and will usually [rack up] cock mileage on a woman faster than a more modestly equipped man.
