Scarring, which mostly occurs during and mainly amongst teenage girls, specifically questions the challenges of integrating the feminine element during adolescence. It will be argued that the resort to masochistic acts of scarring on the body testify to a feminine problem in approaching genitality. This problem is marked by a difficulty to reach a passive position. Conflicts of passivity in a teenage girl can be explained by the specifically feminine difficulty in combining both primary and secondary homosexuality on the same object. A narcissistic continuity from orality to genitality, likely to cumulate potentialities of any trespassing experienced and of any anxiety of loss of love of the object. The clinical case of a fifteen year old girl, starting from projective tests, is used to widen this theory.
