I wouldnt go as far to say we like our farts. I will say we are tolerable towards our own stink and we arent disgusted by it.

Also i think we can force society to be more tolerable towards other people's stink as opposed to "strictly no farting in public places" rule that we have now. Agreed, the brain recognises smells and the idea of good versus bad smell is natural. Tolerance or acceptance isnt and it can be the same for everyone's farts.

We can tolerate our pets shit and clean it. I am sure we can do it for humans.

And yeah human smell, smell of skin isnt disgusting and we arent disgusted by the natural smell of other people we meet.
