If the word voyeurism attracts your attention then just relax you are not alone in that situation. It is a normal sexual interest that attracts every human being in order to explore what is hidden. But it becomes an abnormal behavior if voyeurism becomes a reason for disruption in your different domain (personal, occupational, social) of life or cause the change in your temperament such as you to become more violent and angry. If at any point in your life you feel that somebody is watching you secretly prefer to call the police and complain against that person.
