Actually, I don't see vore it very appealing since merely thinking about food makes me feel bad especially when I am not hungry.
Seeing that done by someone else or just tasting something when I am hungry IRL looks pretty hot but I do not associate the taste with sex.
However, I have zero interest in dead unresponsive bodies and hardly can understand how other people can see anything sexy in that, as fucking the dead body is same as the fucking the hole in the wall or piece of ham taken from the fridge. It is not human it is not in eternal slumber it is just piece of meat which will soon turn into fertilizer.
An exception to that would be if something is done to the dead body to impress someone else.
