No. The main problem of teen sexuality is not that teens are having sex, because our ancestors usually got married in their teens. The problem here is that we’ve pushed when it is permissible for people to become sexual well into their twenties, after they’ve completed post-secondary schooling and created an independent life.

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.

The age of consent is 17; even before that it's not really criminalized unless statutory laws are violated.

You have an interesting relationship with the truth.
