Because one feels ashamed, and the other feels cheated. Both breed resent and when people resent each other they can snap at each other quick. They also can take out their frustrations on others. To answer your question, it's because they can. I've never been mean after sex, I've been flighty and taken off but I've never been outright mean.
Getting angry at someone because of their less than stellar performance, does nothing to help that persons confidence. Is "getting off" more important than encouragement? Or do you only care about having an ******? No matter how you get it.
