This study aims to understand how street young construct their affective and sexual experiences. Individual interviews were conducted with thirty-two street youths in Montreal (18 women, 14 men) aged from 18 to 27 years old. The testimonies were analyzed from a typological method (Schnapper, 2005) that identified five groups of affective and sexual experiences in the street context : criminal success, withdrawal, survival, commitment and avoidance through drugs. The analysis shows that youth from the withdrawal and the commitment groups reported an affective engagement with their intimate partners, while the youth from the criminal success and the survival groups described an instrumentalization of their intimate partners. The ‘avoidance through drugs’ group shows the influence of drugs, which push young people to instrumentalize sexuality in order to satisfy their addiction. This study helps to nuance the homogeneous and threatening conception of the street context by showing the different ways in which the youths mobilized their affective and sexual experiences in order to improve their situation.
