Have you ever found yourself attracted to someone younger than a 12 year old in real life?
12 years old is like right on the border between pedophilia and hebephilia. Most men are hebephiles (at least 45%-50% of men are, probably more).
If you haven't ever found yourself attracted to someone younger in real life, 6-10 years old, I'd say you're completely normal, with a preference for loli/hentai drawings to actual porn.
But like >>22621
said, it's something you need to think about and figure out for yourself.
