How would a person go about demonstrating that they did not consent?
Sure. I don't mint helping with Bible reading. That's actually a pleasure to me.
(Deuteronomy 22:23-29)
23 “If a virgin is engaged to a man, and another man happens to meet her in the city and lies down with her,
24 you should bring them both out to the gate of that city and stone them to death, the girl because she did not scream in the city and the man because he humiliated the wife of his fellow man. So you must remove what is evil from your midst.
25 “If, however, the man happened to meet the engaged girl in the field and the man overpowered her and lay down with her, the man who lay down with her is to die by himself,
26 and you must do nothing to the girl. The girl has not committed a sin deserving of death. This case is the same as when a man attacks his fellow man and murders him.
27 For he happened to meet her in the field, and the engaged girl screamed, but there was no one to rescue her.
28 “If a man happens to meet a virgin girl who is not engaged and he seizes her and lies down with her and they are discovered,
29 the man who lay down with her must give the girl’s father
50 silver shekels, and she will become his wife. Because he humiliated her, he will not be allowed to divorce her as long as he lives.
Notice, in verse 23 and 24, the details are given.
They are in the city. The woman's scream was not heard.
Verses 25 to 27 - In the field, the woman's word was taken, and she was spared, but the alleged rapist was put to death... because she screamed, but could not be heard.
In verses 28, and 29, they are discovered. The girl didn't put up much of a fight here, as in the case of the first. However, the difference is that she is not engaged to anyone (technically married), and God is merciful with them, allowing them to marry.
The man did not forcefully rape her, but he took her virginity out of wedlock. He was not allowed to make her a harlot.
How come God never put my rapist to death? Or anyone else's these days?
God was dealing with the nation of Israel directly - "dwelling with them".
Hence, he personally dealt with matters, when he determined it was necessary.
Just as he did not interfere in the affairs of the world's nations (Egyptians, Canaanites, Chaldians, etc.), he does not interfere in the nations of this world. So he allows things as they are.
The time will come when his appointed king Christ Jesus, takes up complete rulership over the entire earth, Then he will deal directly with his nation - on the entire globe.

This Chapter answers your question in more detail.
We suffer many painful experiences in life. However. these words are a sure, and greatly expected by millions, who make the joy of Jehovah their stronghold.
(Romans 8:18-25)
18 For I consider that the sufferings of the present time do not amount to anything in comparison with the glory that is going to be revealed in us. 19 For the creation is waiting with eager expectation for the revealing of the sons of God. 20 For the creation was subjected to futility, not by its own will, but through the one who subjected it, on the basis of hope 21 that the creation itself will also be set free from enslavement to corruption and have the glorious freedom of the children of God. 22 For we know that all creation keeps on groaning together and being in pain together until now. 23 Not only that, but we ourselves also who have the firstfruits, namely, the spirit, yes, we ourselves groan within ourselves while we are earnestly waiting for adoption as sons, the release from our bodies by ransom. 24 For we were saved in this hope; but hope that is seen is not hope, for when a man sees a thing, does he hope for it? 25 But if we hope for what we do not see, we keep eagerly waiting for it with endurance.
We have that sure hope, while we cope.
