I genuinely believe that all the tabooisation around sex is a holdover from the days where birth control wasn't readily available.
There was an economic incentive for People Who Own Stuff to control procreation, because this allows them to control who inherits their stuff.
There was a personal incentive for most people to control procreation to prevent their children of making A Mistake(tm) by getting stuck with The Wrong Person(tm).
Where there's incentives, they'll wind up being followed. Story as old as time.
Cloaking all that in religion is just window dressing so one doesn't have to admit their true reasoning, but a purely secular pre-contraception society would also have tried to regulate sex.
A TTRPG campaign I wrote and ran two decades ago for a group of friends.
I knew only a fraction of what I know now, was overambitious and railroady - it should have turned into a disaster.
Instead, things just... clicked and we had a few months of gorgeous fun. Years later, one of those friends confessed to still getting goosebumps when a key scene's theme song plays.
(Obviously, a core reason for this working so well was that we were just a great group.)
You tell me what your PC wants to achieve and how. I set the DC to check how well they perform at that attempt (or declare "no roll needed", because it's trivial / impossible).
You want to persuade an NPC? Tell me the gist of your argument and I'll consider how receptive your target is and set a DC for checking how well your PC can present said argument.
(In some cases like "I want to hit them real good with my sword" or "I want to climb up that wall", no detailed description is necessary, we both know what you mean.)
