I'm given to understand that ink and/or writing IS an actual kink. I got into a conversation with someone who knows far more than I do about kinks, and intimated that I liked the idea of people writing on other people. Said kink person was all "what do you like written?"- apparently people do writing/ink kink as part of dom/sub and humiliation sex. I explained that actually, I did not want "owned" "slut" or anything of that nature written on me, and sidled away.

I'm also given to understand that inksmut is a commonly acknowledged fic genre... a couple of people had kittens the one time I wrote it...
