Quality of life is discussed in the paper in the context of human needs. In this conceptual framework, sexual needs are considered as well as their relations with the concept of pathology in social sciences and theology. Prostitution is analysed as a special form of sexual pathology and a social service that fulfils human needs and influences quality of life. The location of prostitution in the city of Bydgoszcz is analysed in details, as well as models of spatial distribution of ‘social agencies’ in the city.
