Sexuality represents one of the most complex aspects of a human being with inherited and acquired anatomical, physiological and psychological characteristics which have appeared through milleniums under the influence of physical, biological and historical-cultural factors. It has been studied by many social and natural sciences, more than any other phenomenon not just related to human beings but to nature in general, as well. Many people consider sexuality to be the force which moves (and stops) the world. Sexual delinquents, more or less dangerous, disturb the public with their behaviour. In the eyes of people, they are dangerous criminals and the society wants to be protected from them. Their agressiveness is the category which connects them to perpetrators against life and body. In addition to psychopathological causes, the essence of their existence, with quantitative and qualitative characteristics of the act related to time and space, is also in sociopathological causes.
