People have been talking about virginity and monogamy for 1000s of years. Men want to know that the children they raise are their own.

It might have blipped a bit since the invention of the pill but women cuckolding their partners has been frowned upon world wide for a very long time.

Sex before monogamous marriage has historically been a big thing.

There's even songs, sagas and religious books that make virtue of it.
