should people care about their partners sexually past? should you really be bothered about how many people has had a taste of the honey pot or joy stick before you appeared in the scene?
if you are one to care, how much is too much body count?

With men it doesn't matter how many ladies he slept with but with the ladies this is very crucial. We do not want an overused gf. If she can give away her puci to everybody she is not a keeper.
