Why is it when man caught having an affair to other woman earns appreciation?

This is crazy!!!! why do men get appreciation when they have extra marital affairs? Common if you men can do it why can women do it too and tell the world that we are also desireable and can give the same satisfactions as the one you are in with. It is no difference. You only need to test drive us and we be able to perform better then expected. Unfortunately you misjudge our capability. We are as good if not better than the woman who can provide you with pleasure.
