Is it normal to want my wife to fart while i’m eating her out?

Skip all that nonsense and have her shit directly into your mouth.

Next time she farts when you aren't having sex, try just nuzzling up to her and say, I know this is kind of weird but when you fart, it kind of turns me on, I think it's hot. And see what her reaction is

Whatever blows your hair back man.

Go eat shit while you're at it! Why not taking a swim in the septic tank?

you can eat out my wife while she farts in your face i just dont want to see it.

Pussy farts (queefs) OK. Raunch ass farts? Not so much.
