RWBY - What do cats taste like?

Can someone clue me into why Vore is a fetish? I mean, I don't just want the answer "Everything is a fetish", I want an answer from a person who actually has a fetish for it.

I mean, I can understand somewhat most other fetishes (Feet, pregnancy, exhibitionism, hell, I can even kind of see where watersports and scat are coming from, even if I do find it disgusting), but vore was never something I understood to be "sexy".

I mean, wouldn't that technically mean you're preforming bestiality every time you eat meat?
