I would say more societal peer pressure than shame, but I don't want to argue semantics. I think that yeah, some of that went away, but another wave in another form is being created right now. Take a look at things like the fitness movement, NOFAP (which I think it's BS but that's beside the point), etc.

A lot of individuals get lost in this cultural transitional period, but I think this always happened. A good example was the hippy movement, they where very drug and free sex positive too. Society as whole will be OK I think, other non-legal checks and boundaries are being set up to prevent a major collapse. Collectively we learn from mistakes and correct for extreme behaviors.
