I had a girlfriend many years ago who was actually cool with my vore fetish and would make short POV vore/mouth vids for me, and would let me stare into her gaping open mouth while we were intimate. Unfortunately that relationship ended.
Of the few serious partners I had that I shared my vore fantasy with, she was the only one that really engaged it. She didn't understand it or feel a need to, she just knew it was what I was into and she was happy to make me happy.
Not everyone will be so receptive, but the strongest bonds you will have are the ones with people you share most of yourself with. So I say once you're sure she's committed to you, go full throttle and let her know the extent of your fantasy and find out in which ways she might be willing to engage you in it.
The less you give of yourself the less full of an experience you'll receive.
