Personally if I had kids I'd rather than they were looking at porn than - injecting / snorting drugs, committing robberies/assaults, shooting up their school and their peers.
Put it this way the chances of death from teen pregnancy are exponentially less than being shot and with contraception and advice on how to use it being applied, lower still....
This obsession with some romanticised "innocence" that lasts until someone is 18 (or in some people's eyes till 21+) has led us into this deranged rabbit hole of stupidity.
If it wasn't for the "think of the children" you could easily solve the lack of sperm donors in this world by paying teen boys to do what they do anyway, except into sample containers rather than socks etc (i'm sure legions of mothers would be glad not to find socks that could do double duty as hammers for one.....), boost entrepreneurship, keep them out of trouble (why join a gang and rob someone when its more lucrative to well....stay home....)
(before anyone reports me, my tongue is firmly in cheek and I am being in NO way serious in anyway shape or form, just indulging in what would have passed up till relatively recently as humour......its sad i have to make that clear...)
