The psychoanalysis of an exhibitionist, who after four and a half months of treatment got himself rearrested in order to escape further analysis, is extensively reported. A remarkable fact is that a younger brother had once been sentenced for the same perversion. The case illustrates very well the commonly recognized features of exhibitionism—feelings of doubt about one's own masculinity and strongly developed voyeurism. The meaning of the perverse act is shown to be a denial of the fear of castration related to an unconscious guilt feeling and at the same time a search for the 'perfectly complete woman'. Unfortunately, the short period of analysis did not allow a profound understanding of the childhood relation with the mother who, as one often finds in the history of exhibitionists, was a highly dominant and sexually seductive person.
