I’m addicted to smelling my own farts. Why?

Unfortunately, this isn’t a joke. I’ve always enjoyed the smell but recently it’s progressed to the point where I’ll cup my hand, fart, then proceed to cup my nose until the smell dissipates. When I’m in public I almost always try to subtly smell them ie: leaning down to tie my shoes etc. To the point where I almost experience FOMO (fear of missing out). Wtf is wrong with me? Does anyone else experience this? I mean it’s literally progressively getting worse and worse similar to an actual addiction. It’s worth noting anyone else’s are completely repulsive to me.
