Why is rape a crime beyond just being assault? The answer is that it is an evolutionary crime against a woman to force her to have children with a man not of her choice. In evolutionary terms, our main purpose is to reproduce. The success of our genes is determined by how well we reproduce. For a woman, one of the most important things that she can control for reproduction is the choice of the man to have children with. To force her to have children with a man not of her choice causes extreme emotional pain precisely because it is so important in evolutionary terms.

Compare this to the rape of a man. If one thinks of a woman raping a man, it is almost comical because it is so meaningless. It is meaningless because it has no evolutionary impact, or may even have a slight positive impact for the man. Women can only have a limited number of children, so they must be selective in sex. Men can have an unlimited number of children, so men have no need to be selective in sex. A feminist may raise the issue of a man raping a man. But this is simply assault and nothing more. So the point is that rape is a crime against women, not men.
