So YouPorn is a medical device now. Seriously: those are not the sole studies showing those evidences. There are older with the same results. Religion and movements that prevent masturbation are disturbing from the point of view of the sexual development of teenagers.

Let’s not forget the kids before puberty. Today’s “hysteria” is alive and well — it’s called ADHD and it involves overdiagnosing rambunctiousness and prescribing amphetamines like Ritalin or Aderall to medicate the “problem” away instead of making the kind of changes to the school system that Finland made. A lot of societies have often chosen to use medical interventions on the individual instead of fixing the underlying problems. In the case of ADHD:
1) both parents work to afford the rent and “self-actualize” themselves 10 hours a day at corporations https://magarshak.com/blog/?p=286
2) they stick their kids in public schools where administrators treat them as a number and they have to sit down and shut up for long periods
3) many kids (especially boys) have too much energy to just sit still for so long but the system needs to teach them how to be good corporate drones (even though by the time they graduate corps won’t need them to wirk that way due to AI)
4) climbing trees and running around creates liabilities in the US, keeping the kids docile keeps them out of trouble https://www.smartparenting.com.ph/parenting/big-kids/the-sim...
ADHD is today’s hysteria.
