Dude where did you get those numbers? That's bullshit...Even in national poles lifetimes partners never come even close...Are you telling me national poles are say 80 men off each broad?...lol
Dude, never believe National polls, men overstate who they've been with, and women understate (high mileage is a no-no in cars and women).
I've known women who, rationalize 50 men down to 15. And 20 men down to 5, I want you really think about that.
Basically, you will never know, and you don't want to know. Leave it at that, and enjoy your time.
