I don't normally look at child porn because it doesn't interest me, but I have seen it on two occasions. Once when I used to chat to a guy who sent me a picture of a little girl sucking a man's cock. And on another occasion when I used to chat to a woman who told me that she forces a 12 year old boy that she babysits to fuck her and her friend. She sent me a pic of it. Whether those pics were real or not, I don't know and I don't care.
I do like rape videos of teenage girls being raped. They're hard to find though.
I prefer to watch snuff videos more than anything else and I've seen quite a few over the years, of people being strangled, stabbed, suffocated, shot, drowned and hung. Mind you, 95% of them were fake and the others I can't be sure of as they were sent to me privately by someone I knew.
