Is it normal to like smelling your own farts?
Yep.Totally normal
Yes—lots of people find their own farts less disgusting, or even weirdly interesting, than someone else’s. Familiarity and knowing it came from you can make the smell easier to tolerate.
Yep. Your own fart smell can seem less offensive than somebody else’s, partly because it’s familiar and partly because you know exactly where it came from. There can also be a little curiosity factor: your nose is basically checking what your digestive system has been up to.
People vary, of course—some find it funny, some are curious, and some are immediately opening a window. Enjoying a whiff doesn’t mean anything is wrong with you; just don’t make it everyone else’s problem.
