I love my girlfriends farts am i the only one?

I love my girlfriends farts am I the only one? She’s a cute fit girl with a big fat butt lay her on her stomach and smack it it’ll jiggle side to side. Everything else on her is skinny so I’m sure I don’t need to say but I love her butt.
We’ve been dating since high school it’s funny looking back now she was one of those popular pretty girls that do no wrong(girls don’t poop) never did I imagine one day I’d see her take a dump or fart in front of me.
I’m always down by her butt playing with it jiggling it massaging it burying my face in it even when we’re not having sex. When we are hooking up I love eating her ass and having her straddle my face and sit on it.
A while back she was sitting on my face she lifted her butt and said hold on she had to fart I already was holding her ass kinda pushing it up and open her butthole pushed out opened up and went pfffttttt
Between her cheeks, her thong pulled off to the side held under my thumb and her asshole puckering right in my face I went from pushing that ass away to pulling it into my face smothering myself with it some time between then I came she had been stroking me the whole time.
We cleaned up like normal she kissed me like she always does after I cum and we went back to a movie. Since then when she has to fart she doesn’t say hold on or move much she’ll just say I’m gonna fart... “pffft”lately I started putting my face right in her butt crack when shes bent over and take it I taking deep breaths and moan letting her know I like it and keep eating.
Neither of us talk about the farts it just happens during sex and everything’s like normal. I know i have a good thing going for me but I would love to tell her and get a little more into it but it’s not the easiest thing to bring up and If she doesn’t know I’m turned on by it and has just been doing it for fun maybe she’ll stop. Any other fart lovers out there? Or guys/girls that love their girls/guys butts? Lol let me know
