Might be an odd question, but let’s be real, ghouls are pretty unique physically; no noses, inhuman eyes, ~ribbed for her pleasure~. Do you think a Ghoul Kink is a known phenomenon and, if so, which ghouls take advantage of it? Are there any that avoid a partner who wants a ghoul specifically so they aren’t objectified?
Fun ask! Ghoul fetishization is definitely a thing, even in canon. I've seen it mentioned a lot in fan works, but there's also at least a couple mentions of ghoul fuckery/fetishization in the games. New Vegas, especially, is pretty forward with the idea that there are people who want to get down with ghouls. You can recruit Beatrix Russell, the hired gun employed by the Followers of the Apocalypse, to work as a sex worker at the Atomic Wrangler, as the twins who run the place are looking for a ghoul for a high-paying regular client who has specifically requested one. There are also multiple ghoul sex workers employed at Gomorrah, both male and female, which implies demand for sex with ghouls on the Strip. Medical records can be found that note possible physical side effects of fucking a ghoul, which means it happens frequently enough for doctors to note common outcomes.
For the record, I'm looking at this more from the angle of pure fetishization (bad, dehumanizing) rather than just having a higher than average level of attraction to ghouls (acceptable, sexy). When it comes to the latter, I don't think most folks would have an issue.
