"Why do we do oral sex therapy...?" The purpose is to stop the increasing number of sex addicts from becoming sex-averse due to masturbation, and to make them realize that having sex with a woman is more enjoyable than masturbation. The first stage of treatment is 'oral sex therapy', and the second stage is 'vaginal oral sex therapy'. Patients undergoing treatment sometimes experience withdrawal symptoms and are unable to control their masturbation, leading to frequent emergency room visits... This is a current social issue in Japan. The goal of the treatment is to reduce the frequency of masturbation and make patients desire sexual intercourse with women.
