Working from clinical interviews with educators, the authors highlight the specific features of accompaniment in sex education for teenagers in care. The professionals stress in particular the history of an adolescent girl showing how her masochistic strategy aggresses any form of expression of a feminine voice in the learning process. Recalling the distinction between passivity and passivation, they showed the issues at stake for an educational attitude open to addressing feminine issues as being the only basis for effective teaching that resists the temptations of action, seeking ascendancy and disinvestment or relinquishment. This article emphasises the ethical position of the psychologist, providing support in the elaboration and the understanding of adolescent behaviour patterns of a morbid nature with professionals in the social sector.
