IIRC a more likely explanation is that kids spend more time online these days and less hanging out with friends and getting in trouble. People are happy about the dropoff in teenage pregnancies, but IMHO this is a harbinger of falling marriage and birthrates. In a decade we could look like Japan with a stagnant population and people in a near panic that the kids aren’t getting married and moving out and starting a family.
I will say that the theory that easy access to porn will turn kids into insatiable sex fiends seems to be disproven.
