I know that but I'm talking about the actual taste of blood in some steaks I've had, I don't know if it seeps into those juices but there's an obvious blood taste, some better prepared steaks have it, some don't. Maybe it's just better cuts or something.
What kind of steaks are you eating? I've had plenty of steak and I've never once tasted blood when cooked at a shorter length of time.
From my personal experience, a lot of people find the concept of eating steak that isn't well done odd and off putting. My family for instance prefers well done steak. Despite this, my step dad likes to mention offhand about me making steak for the family a few times-- and I never cook it well done or above medium.
