Hmm. I know this is a bit off-topic, but I think you could probably apply this line of thinking to most of the Marvel U, especially the mutants.
I'm CERTAIN - if this were the real world - mutants and mutates (that's the term, right?) would be a big kink for some people. I'm sure more than a few mutants have had creepy power-fetishist boyfriends and girlfriends.
