Differing degrees of rape?

[lifesagift]

There are certainly varying degrees, but every single one is without excuse, and should be punished severely. I support the death penalty for certain instances of rape without death, but never mandatory except maybe upon a second conviction (and obviously as an aggravation of murder).

Except possibly A, every scenario in the OP is rape in one form or another.

Both of these replies actually state that there are different degrees of rape. But don't necessarily agree where to draw the line....
