Can a man tell if a women has slept with another man?

Answer There is only one real way of knowing and that would be if she was a virgin and all of a sudden she's no longer a virgin. Other than that there's no way to know unless she tells you. There is an old expression that goes like this. You will never miss a slice off a cut loaf so if a woman has sex with fifty guys you will never know and that same thing can be said of guys. There are no meters on our sex organs.
