It's a function of our society becoming more puritan and conservative in the past 10-15 years. This has been a slow burn.
We are back to perceiving viewing boobies as an existential threat to people. Currently, sexuality is being demonized all around, and sexual morality is once again becoming a currency in society.
I encourage people to talk to some Gen Z kids. They're much more puritan than millennials. They're focused on virginity and the moral superiority of monogamy. It's bizarre.
