No clue how this became such a big taboo in Abrahamic religion,
Iirc it's about not "wasting" life essence.
Genesis 38:9-10: But Onan knew that the child would not be his; so whenever he slept with his brother’s wife, he spilled his semen on the ground to keep from providing offspring for his brother. What he did was wicked in the Lord’s sight; so the Lord put him to death also.
It's that Monty Python Every Sperm is Sacred song, but unironically
One could presume that in an agrarian/pastoralist society in a semi-arid region, high birth rates were socially desirable to constantly add laboring hands to the fields and flocks
Nah, the Onan crime thing is about Levantine Marriage. Basically if your brother dies you're supposed to marry his wife and have kids, and legally those kids are your brothers kids so his bloodline keeps going. It's a really important cultural thing. Onan's crime as that he was banging his brother's wife without knocking her up, so he was basically committing a crime against his brother and his family that was really serious in the culture of the time. Had nothing to do with masturbating.
Basicalyl Onan was being a shit because he didn't want to take on teh burden of raising his brothers kids. Seriously, has absolutely nothing what so ever to do with masturbating or pulling out or anything else.
I mean the guy was literally named after the act of masturbation, a sort of ancient precursor to a Coomer, I think we can agree he was an edge-case. :putin-wink: :
it was pretty obviously the fact he was disrespecting the rights of his new wife that they held. tbh I consider that a weird right but the issue was the fact that he was treating her without the albeit deeply weird rights she was due by custom
On the Christian side, Paul and Augustine are largely responsible tbh. Dudes were so ashamed of their horniness that they (namely Augustine) wrote extensively about how it's ontologically evil to wanna eat ass all across town lmao
Notably Augustine spent most of his adult life bouncing around sex cults before deciding that actually sex was bad and abandoning his mistress and illegitimate child to die on the street.
Edit: im not very studied in talmud at all but this reads to me less of dude being an incel and more about laws on who you can and can't have sex with as laid out in the Torah.
It's like 1800 years of Rabbis arguing with each other about every fucking thing you could imagine and a surprising number of things you never thought of. These guys have sat down and hashed out moral conundrums you would never dream up in your wildest imaginings.
