Her swords only cut flesh to that degree when plot needs them to. Same with the rest actually. Though the anime censored bloodied cuts and gashes out. The only real time where she drew red blood in the anime was in the OVAs and that was joke context, much like the instance Happy said. But in manga, Erza has yet to actually inflict life-threatening wounds and even ones that would result in heavy blood loss did not lead to death or intense agony. So far it was just flesh wounds, not organs plus we hardly ever saw her swords dripping with blood. See?
