Is it normal to like the smell of your own poop?
Depends.It depends
Yes, some people don’t mind or even like the smell of their own poop. It’s a personal reaction, and by itself it usually doesn’t mean anything is wrong.
People can be more tolerant of their own body smells than other people’s, partly because they’re familiar. And smell preferences are weirdly personal: what one person finds gross, another may find oddly satisfying.
Plenty of people still find poop smell unpleasant, so there isn’t one universal reaction. If you mean you like it, rather than noticing a sudden change in how your poop smells, it’s generally just one of those harmless quirks.
