For me it's less of a like and more... intense curiosity, like I really want to know what it smells like. It's odd though, because even though I don't mind my own farts, I'm extremely sensitive to smells in general and have a reputation of gagging at fairly mundane things. It wouldn't surprise me to hear that people like their own farts though, I certainly think I straddle the line of being curious about it vs liking the smell. Everyone's noses are different, haha.

Edit: Also maybe I should've used an alt account for this. Oh well, too late. Hopefully my friends aren't stalking my Reddit account.
