The concept of sex addiction first appeared in the 1980s, though it has its roots in the history of the anti-masturbation movement that flourished in America a hundred years ago. Masturbation doesn’t make you go blind, and sex is not a disease. But these facts haven’t stopped people from falsely proclaiming that too much sex is bad for you, too much masturbation will turn you into a pervert and too much porn will turn a person into an uncontrollable pedophile or rapist.
