The author first considers the analysis of this question by pointing out two of the clinician’s stumbling blocks : the difficulty of speaking about psychic structure in the teenager, given the mobility of his mental functioning ; and the association of certain aspects of the crisis of adolescence with a revival of the infantile polymorphic perverse phase. Secondly, he studies three specific clinical situations : defensive movements of a perverse nature ; sexual and moral perversions which appear at this age ; perverse links where a paedophile, incestuous, corrupting or perverse-narcissistic adult takes as object a teenager, who becomes his victim-accomplice.
