There is definitely some level of abstraction between real and drawn, which is why you'll see real pedos who aren't into drawings and vise versa, but what exactly causes it, and how common each is to each other, or to someone who can go with both, I do not know.
Maybe in some cases it's simply the knowledge that it's not real, like what you see with people who don't mind graphic spatter movies but can't stand real gore.
