I'd say we're living in a post free love world. Sex and promiscuity is at once encouraged, and yet, stringent standards are loudly preached about. The end result is certain people having a great deal of sex and certain people having much less. Promiscuity is encouraged in women, but only the top 10% of men benefit from it.
The end result is less sex overall because there are less monogamous relationships, but women consistently sleep with the same small population of males. The unhappiness from that in turn leads to many of those same women moaning about consent, patriarchy, etc. and browbeating other men while being willing to throw those standards out the window to fuck aggressive, attractive males.
When it was the norm, lifetime monogamy and pre-marital chastity (even if many people did not live up to it completely), produced more monogamous couples having more sex than the current population of dysfunctional, single adults.
