Social, juridical and police institutions contribute to make public the private life of prostitutes. Society reinforces this confusion between the public and private spheres by considering venal sexual intercourse as the sale of the individual's most intimate part, of the woman's soul. We show how the street prostitute responds to people's look on her by redefining her field of intimacy. Our study is based on a previous quantitative research work carried out in the 90's on the streets of the city of Lille.
