The author attempts to test the hypothesis of traumatic repetition with both positive and negative valences by analysing the case of a young male chemsexual. The aim is to investigate the meaning that this repetition takes on through his practice of sexuality while under the influence of drugs, and, further upstream, with regard to a life journey marked by numerous accidents and setbacks. In so doing, the author seeks to account for the dynamics of the supposed repetition and for what this reveals in terms of early flaws. On this path of elaboration, he also offers an analysis of the first experiences of tuning with the mothering environment, as well as the influence of these experiences on the Winnicottian mirror function. The repercussions on the process of subjectivation will also be examined in order to put into perspective the practices under the influence of drugs that are in question, and which seem to be situated, perhaps paradoxically, at the beginning of this process.
