I like girls farting

I have a fart fetish. I've had my ex's fart around me, but I've never had the nerve to tell them it turns me on. I found out when my ex was enjoying herself with her own smothering fetish with her butthole on my nose so I couldn't breathe, I enjoyed this as well, when she farted directly up my nose and turned me on more than ever before.
I want to tell girls that I enjoy it when they fart and it's sexy to me. I have had girls sit on my face and I enjoy it but I want them to fart in my face, nose and mouth. Is this normal?
