Is it normal to be turned on by my girlfriend's belly?

Recently my girlfriend and I had a fun night. We got on the topic of her belly pooching out and how she had a big food baby from a burger she had eaten. I've always been into food babies and I playfully told her it was hot. She then sent me a picture of it, which she had never done before. I immediately became turned on, and then she took another picture, and then another one. We then got on the topic of the fetish seeing how turned on I was and she said she didn't mind and would send me more (long distance relationship). I think her belly now is one of the most attractive things about her and I want her to stuff it even more but I can't just say "Hey can you do major stuffing for me". I want her to eat some more so I can see it bloat and really badly want more pics of her belly. I have never been so turned on before by a girl and for so long having those images of her bloated belly stuck in my head.
