Really? I've heard of rapists who have gotten quite upset when the woman told them she would get an abortion. Seems they thought, like you, that they had a moral right to make her bear their children.
You're not including false concepts like 'rape within marriage' or 'date rape' or whatever, are you?
It's only rape if the dude is wearing a balaclava, and the women kicks and screams the whole time.
