Fair enough, I didn’t think you meant the free love movement. I think the reason those numbers are falling is not because the world is more prude, though. There’s a ton of factors at play - money, entertainment, and laws.

Social events/dating is prohibitively expensive for a lot of people nowadays and there’s even less reason to do it now that technology has taken away a lot of the reasons people go out. So people are meeting less in general and therefore hooking up less

Women’s rights are also being eroded across the world and an accidental pregnancy is not worth the risk. Can’t get an abortion, can’t afford to be a parent. There’s more awareness of STDs and a LOT more awareness of sexual predators…not to mention awareness of how the courts often let them get away with it.

Another thing I just thought of - it’s financially beneficial to “settle down” with one person. More and more people are incapable of affording housing on a single income. I’ve been joking about making a dating app profile with the bio “HOMEOWNER LOOKING FOR A WOMAN TO SPLIT THESE MORTGAGE PAYMENTS WITH”
