I think its a lot more complicated than that. Cultural attitudes to what is socially acceptable for sex and marriage varies an awful lot. Sure in 19th century America a woman unmarried by 20 was regarded as an "old maid". But there was much less pressure in the eighteenth century and in the seventeenth it was unusual for people to marry before 30 - and pre-marital sex was extremely uncommon.

Bottom line is there are a lot of reasons for the current problems we have with sexuality.

People have been having sex for forever throughout history married or not.

It’s just the in your face sexuality is more prevalent today.

It is more complicated. First, due to poor health, the onset of puberty was also at a later age. Girls didn’t start menstruating until they were 17 or 18, compared with 12 or 13 today. Second, the Puritans were actually fairly ribald. They weren’t that pure.

People were so busy farming, gardening, cooking, laundering, sewing their own clothes, etc. that the time and and energy for sex was severely limited. We don’t know if pre-marital sex was uncommon. Fifty years ago, a South American friend told me that women frequently engage in anal sex so that they will be virgins on their wedding day, or to avoid pregnancy. On the whole the men didn’t seem to mind. Could this have been a factor in earlier centuries. Also before men codified and monopolized the medical scene, women healers and herbalists knew ways to prevent pregnancy and no doubt were frequently consulted by women.
