I guess I can see where you're going with the face-paint/tattoos for KanKiba. As far as I'm concerned, so long as you respect that other people like different pairings it doesn't matter how strange what you support is. My friend and I (the other SasuKiba fan) went through FanFiction.net last year to find all the pairings we could for Naruto characters, and trust me, we had some strange ones. Last count, Kiba had 14 heterosexual pairings and 17 homosexual ones.
Of course, Naruto, Sasuke, Hinata and Sakura came top for their categories (although, Sasuke has 20 more gay pairings than straight ones. Not including SasukeXHousehold plant and SasukeXKishimoto.)
