How is it equal if he wants something no one wanted to give him?

You're right. That actually means that he is unfairly disadvantaged. She gets what she deserves but he doesn't.

It would only be equal if there was someone who was itching to fuck him purely for the experience of fucking him, but forces were keeping her from doing so.

I don't know what you mean by that.

If you think you're owed something that no one wants to give you, to the point where you are angry that someone doesn't want to willingly give you something, then that is putting your needs above others.

Insane. What about the American revolution, abolition, civil rights. Those people were putting their needs above others by being upset about their situations?

If animals were owed sex simply by existing, there would be no birdsongs, or mating rituals in general. Survival of the fittest includes ability to get a mate despite by adapting to changing environments.

I'm actually kind of glad that we became civilized beings with free will. So we don't have to conduct our lives like wild animals. If it was still survival of the fittest, the guy could just over power a woman and have his way with her.
