Why Do We Like The Smell Of Our Own Fart?

I can assure you I don't like the smell of mine - nor does anyone else who's unfortunate enough to be in the room with me at the time. I come from a family of farters, but what makes things worse in my case is I have Lupus, an autoimmune disease which affects the organs. It affects my lungs and my bowel, so my farts come out with a government health warning attached.

I think its because we're used to the smell. It's our body, so we have a tolerance for it. When someone else does it, it's a bit different. It's a foreign smell that we are not prepared for mentally so its a bit jarring when it occurs.

i dont like it either although its tolerable for me. i would even tell someone who just hate me upon smelling it that i didnt ask them to smell it in the first place
