I think the easiest and most boring way to explain it is that you either like X thing or you won't quite get the appeal of said X thing. I mean there's nothing wrong with not liking certain things or not understanding the appeal, I'm sure even those who find diapers appealing have subject material that they can't grasp or understand why people would like it, etc.

I know that isn't the answer you're probably looking for, but the appeal is going to have it's varying degrees of what people find appealing about it to the point where there isn't a one given answer. For myself, I think of the appeal as being linked to humiliation in softer tones that can vary into more extreme tones. Humiliation aside, it can come off as being cute or adorable depending on the situation for a character. (Note with my mentions is that I'm talking purely fictional characters and writing wise, scenario and the like. Real life situations and stuff doesn't really appeal to me, but for other people it might and that's okay too.)
