A poll would be the best way to find out people’s preferences, but if you want to get a rough idea right now, there’s this thread is from a few years ago:
My general impression from skimming a handful of people’s old tier lists is that slob, farting, and sweat tended to be ranked low on people’s list of preferences (though not as low as, say, major health issues). That’s not to say there aren’t people who are into those things, but they’re likely to be off-putting to people who don’t have those fetishes, even on this site. Thus, it takes more effort to include them in games in a way that won’t repulse part of the potential audience.
