Consensual is preferred but noncon is not a trigger or squick for me right now so go for it if you want.

Squicks: scat, excessive blood
Kinks: anger; a pre-sexing fistfight that ends with awkward manly hotness; they hate each other; tullius is contemptuous of all things Nordic, and this pissed off Ulfric to no end.
