She's a homunculus with some kind of programmed behaviour and very little ability for autonomous action and emotions.
The problem really isn't a lack of spine.
Would she resist if you tried to gently rape her?

She's fucking arfiticial.
But she is warm.
Because she's still a living being and basically a human (or shinigami, but neary the same anyway).
