There has always been an interest in porn, going back to when the photographic camera was first invented. In the '50's, '60's and early '70's it was magazines and 8mm film then with the invention of the VCR the porn industry literally exploded, now you could rent or buy hours of porn and watch it in the privacy of your own home, before there were X-rated theaters where one had to go but many did not want to be seen in "that" part of town. I worked at a VCR tape rental place, porn was about 50% of our rentals, now we have the internet in where the amount and variety is staggering and 2-3 mouse clicks away, maybe a computer can be "locked down" so porn sites cannot be viewed?, I don't know how effective it would be though, kids have a way of getting around parental controls. I guess IMO the only real downside is young teens exposed to limitless amount of porn will wind up viewing a female as a sex toy and not a person or will spend so much time fapping to all the fresh porn he will not bother to try and initiate a real relationship until much later than normal.
