Vampires: why does your character drink blood? Options

[Lady Saga]

I am having trouble with this one, and need some ideas. Why does your character drink blood? Why do they feed?

In Oblivion, becoming a Stage 4 vampire caused the majority of NPCs to be repulsed by our characters. They technically did not have to feed, but at least once the feeding was done, the NPCs stopped recognizing that our chars were vampires. This essentially gave our characters a reason to feed, at least.

But in Skyrim, this is no longer so (assuming Dawngurd is installed). The NPCs treat our characters with mild suspicion at best, but going from Stage 1 to Stage 4 does not actually cause any wanton sorts of behavior from the world.

So why does your character need to feed? What RP ideas have you all come up with?

With my vampire characters I always tend to play them as Cyrodiilic vampires so they want to feed to remain hidden from society. I personally find the Cyrodiilic vampires the most interesting because of their deception and the way they hide in plain sight like the Count of Skingrad.

I don't play as a vampire, but agree 100% on liking the idea that by drinking blood they can live amongst mortals without our knowledge (like Seridor) - imagine the possibilities for roleplay and stories!
