I feel like that is suuuuuuper subjective. Everyone is gonna have a different opinion on that and knowing how people can get it could potentially cause discourse xD
Likewise depending on the fiction, what might be kink for one species could be vanilla for another.

I dont think I personally like the idea of labelling one species kinkier than another because a lot of that segmentalistic line of thought derives from and harkens back to racial profiling which icks me. It's along the same line of saying all orcs are evil.
