The ego of the pervert, frightened by the mingling of aggressive with libidinal impulses, flees from the feared and sought object. 'Eroticization of defense mechanisms or of anxiety with the consequent possibility of orgasm is the specific characteristic of sexual perverts whereas in neurotics this eroticization, even when it exists, is never recognized as such by the ego and in no case leads to orgasm.' One can treat the pervert satisfactorily only when neurosis coexists.
