or are supposed to be scary are the ones that most get my heart beating (in a good way), as long as there's no blood or real violent content. Kind of weird, I know our sense of fear is somehow tied to arousal but I don't get a feeling of being afraid, I get a strange feeling of warmth...

Could someone help me find some pictures like that? No blood or dismemberment, please. Bonus if there's vore involved. Tyrannosaurs are preferred. Dragons are OK too.
