Pornography is as old as human sexual activity. No one should be forced to do it and should be consensual on all levels.
Its should be rigorously controlled so that the parties involved are not exploited or endangered. I have met women and men on the whole scale of sex work. From the exploited addicted to pro porn feminists and lesbians who see it as there personal right to express them self in there erotic and sexual nature as they see fit.
I can not see how this aspect of human sexuality can be stopped, you can?t change human physiology .You can only maintain rigorous safeguards and regulation to help the vulnerable, both male and female involved in the trade.
You cant turn the tide back, but you can build a flood wall.
