sex is not meant purely for procreation.

biology put things into humans like sensations, hormones, urges.. offering pleasure, happiness and contentment.
this is nature, natural and biological fact from millions of years AGO
meaning sex is natural and pleasurable before religion said no

its only HUMAN politics and religious law that then limited sex to be portrayed as purely for procreation

what you learn is that history shows that before religion people had pleasure, people had vices.
but with that came the risk of spreading diseases and causing harm via non-consensual sex(rape)

so laws(religious scripts) were created to limit these. and over time religious extremists took these safeguards too far and made sex sound like its evil and should be avoided at all costs.

..
sex for pleasure is not 'contemporary' or 'modern', it is INFACT older and more natural than the religious script propaganda
religion is actually the 'contemporary and modern' change to civilisation.. not sex.

you can spot that religion is contemporary, and that religious laws were based on safe sex. because ever since condoms were invented and awareness of asking consent religions changed their stance on their laws and made it so gay, unmarried, sex is no longer a sin(against their law)
