Is there a way we can find out?
Let's put it this way: I'm twice as old as you, and I've consumed gore material since I was around eight, or even earlier. I never had a particular fascination in it, but I was also never repulsed by it. For me, it's simply always been there.
I would argue that there are two types of gore, a pornographic type (gore for the sake of gore), and an aesthetic type (gore fore the sake of completeness or realism). Evidently, a site such as rotten.com (which was one of the first internet sites I've ever visited, because it was cool) displays gore of the pornographic type. I've never been interested in that, but as I said, not repulsed either, so that I consumed a lot of it with my mates. But I have always watched a lot of violent movies, and during my puberty, horror movies were indeed what I was interested in the most. Gore just comes with that, the same way you don't have to watch porn to see tits... they're in every other movie anyway. In the same sense, I used to draw cartoon doodles which had a lot of gore in them, not because I was particularly keen on drawing gore, but because I often drew scenes of cartoony violence that demanded it. I'm not particularly interested in violence either. Again, I just consider it an integral part of narrative fiction - it's in pretty much every movie. Not all my doodles were violent, but all of them were over the top in a very cartoony way. And cartoony violence simply lends to the funniest results, and that was all that I ever cared for. A devil ripping out an angel's heart simply has a certain quality to it beyond any sort of pornographic fascination with either violence or gore. Plus, like any self-respecting teen, I simply wanted to shock and offend. My parents, my teachers, my classmates... you have to push the envelope for that.
