>b-because i say so! Repeat after me, SEX IS BAD!!!
In reality many psychological issues stem from suppressed sexuality. Sex is natural, healthy and good, aversion to sex is unhealthy, un-biological and can have serious impacts on physical and mental health.
Pornography is a healthy and normal manifestation of human sexuality. Nothing wrong with looking at naked body or two people happily fucking. However, some really fucked up fetishes and preferences that are harmful or unpleasurable for one side obviously come from repressed libido that eventually exploded and manifested itself in deviancy.
