Voreophilia?
When I was a child some of my strange fantasies would be like that (not sexual don't worry) so I know what the fetish is and how it felt, though it's gone now.
From what I know if you are a voreophile you either have a fetish of confinement within a creature/human's body or one of containing another's. Although it is about eating or being eaten I think cannabilism is different cos it's actually to do with killing, cooking and eating people in small bits, all three are actually a turn off for most voreophiles unless you're a shreddie (I did reserch, it's interesting). Cannabilism is either a seperate fetish therefore or like someone mentioned you might just like the taste. I hardly think you could swallow a living person whole...
But because of limited greek words we'll have to call it vore, so there you go.
