Courtship Disorder Theory

A theory of sexual offending advanced by Kurt Freund that postulates that sexual offending occurs when a person’s sexual behaviour becomes fixated at one of the four phases of human sexual interactions: (1) looking for and appraising a potential partner; (2) posturing and displaying oneself to the partner; (3) tactile interaction with the partner; and (4) sexual intercourse. Fixation at stage 1 results in voyeurism; at stage 2 in exhibitionism; at stage 3 in frotteurism; and at stage 4 in rape.
