What is your favorite part of the fetish?

From what I’m gathering, it seems like there is a lot of different parts of the fetish that some people like the most. Usually smell and sound. I seem to like all of it lol, especially the taboo side of it. And if it’s coming from a really fat ass too lol. I’m curious to what people’s favorite part of the fetish is/why they have a fart kink in the first place :)
