I don't do a lot of horror movies, especially not torture porn. It's not really the gore that bothers me too much, because in action movies and war movies there's plenty of it. It's just the torture aspect and the overall shocking nature of it.
As far as comics go...Gantz was too far, but Attack On Titan is fine.
And then of course there's the Death Metal\Deathcore I listen to, once again, I don't listen to bands that embrace the whole torture porn concept. So bands like Cannibal Corpse, and Infant Annihilator are out.
Now, Thrash Metal has a lot of violence and bloody lyrics, but it's usually more along the lines of a war movie or action flick, or a thriller kind of movie, so bands like Exodus, Warbringer, and Slayer are the limit.
Video games I don't have an issue with really. But I don't play horror games.
Real life...um...I'm out if it involves torture, anything with fingernails, and eyes. I read plenty of scientific nature books as a kid, complete with pictures of shark attack victims and parasite infested kids. So my tolerance is a little bit high. But maggot infested wounds will make me nauseous xD
