Yeah, it's so unnatural it was only observed in dozens of different species. And no, actually, in many countries, pre-colonial ones especially, it was actually considered more-or-less a normal part of human sexuality.
Biblical Law
"Biblical law" is worthless, sick, disgusting bullshit not even The Domination of the Draka would consider a model to emulate.
Deuteronomy 21:18-21 "If a man has a stubborn and rebellious son who does not obey his father and mother and will not listen to them when they discipline him, his father and mother shall take hold of him and bring him to the elders at the gate of his town. They shall say to the elders, "This son of ours is stubborn and rebellious. He will not obey us. He is a profligate and a drunkard." Then all the men of his town shall stone him to death. You must purge the evil from among you. All Israel will hear of it and be afraid."
Deuteronomy 20:10-16 "When you march up to attack a city, make its people an offer of peace. If they accept and open their gates, all the people in it shall be subject to forced labor and shall work for you. If they refuse to make peace and they engage you in battle, lay siege to that city. When the LORD your God delivers it into your hand, put to the sword all the men in it. As for the women, the children, the livestock and everything else in the city, you may take these as plunder for yourselves. And you may use the plunder the LORD your God gives you from your enemies. This is how you are to treat all the cities that are at a distance from you and do not belong to the nations nearby. However, in the cities of the nations the LORD your God is giving you as an inheritance, do not leave alive anything that breathes."
Isaiah 13:13-16 "Therefore I will make the heavens tremble; and the earth will shake from its place at the wrath of the LORD Almighty, in the day of his burning anger. Like a hunted gazelle, like sheep without a shepherd, each will return to his own people, each will flee to his native land. Whoever is captured will be thrust through; all who are caught will fall by the sword. Their infants will be dashed to pieces before their eyes; their houses will be looted and their wives ravished."
Numbers 31:14-18 "Moses was angry with the officers of the armythe commanders of thousands and commanders of hundredswho returned from the battle. "Have you allowed all the women to live?" he asked them. "They were the ones who followed Balaam's advice and were the means of turning the Israelites away from the LORD in what happened at Peor, so that a plague struck the LORD's people. Now kill all the boys. And kill every woman who has slept with a man, but save for yourselves every girl who has never slept with a man."
Exodus 21:20-21 "If a man beats his male or female slave with a rod and the slave dies as a direct result, he must be punished, but he is not to be punished if the slave gets up after a day or two, since the slave is his property."
Ephesians 6:5 - "Slaves, obey your earthly masters with respect and fear, and with sincerity of heart, just as you would obey Christ."
1 Timothy 6:1 - "1 All who are under the yoke of slavery should consider their masters worthy of full respect, so that God's name and our teaching may not be slandered."
Leviticus 25:44-46 Your male and female slaves are to come from the nations around you; from them you may buy slaves. You may also buy some of the temporary residents living among you and members of their clans born in your country, and they will become your property. You can will them to your children as inherited property and can make them slaves for life, but you must not rule over your fellow Israelites ruthlessly.
