I’d like to go a bit deeper.

I don’t think people invented socially controlling practices because they found religion, I think they found religion to frame the invention of socially controlling practices.

Masturbation is a gratifying act that relives pressure to settle into a rigid domestic arrangement that serves to make more workers and soldiers, and create dependents that need fed, and whose well-being would be threatened if a parent became defiant and provoked the ire of elites.

Masturbation is good for the individual at the expense of the nation and its rulers. So it’s inevitable that priests would decry it as an affront against god, as that’s historically been their purpose.
