Within the depth-psychology corpus, masturbation occupies a remarkably diverse theoretical terrain, moving from Freud’s foundational developmental claims through Hillman’s archetypal rehabilitation to clinical case-study usage in Abraham, Jung, and Grof. Freud establishes the term’s central problematic: infantile masturbation is treated as a near-universal phenomenon linked to erotogenic zone development, thumb-sucking, and the first emergence of auto-erotism, while its suppression generates neurotic consequences that persist into adult sexuality. Karl Abraham extends this framework, demonstrating through detailed case material how masturbatory history underwrites later symptom formation, dream-states, and disturbances of libidinal economy. Jung, by contrast, contests the Freudian concept of ‘infantile masturbation’ on biological grounds, arguing it conflates a presexual nutritive stage with genuine sexuality, while his word-association research treats masturbatory complexes as detectable sources of self-reproach and repression. The most radical revaluation arrives with Hillman, who refuses pathologizing and moralistic framings alike, insisting that masturbation belongs archetypally to Pan — and that its suppression destroys not merely a physical act but an entire psychic constellation of fantasy, shame, and natural compulsion. Otto Rank reads clitoral libido in masturbation as the woman’s unconscious approach toward prenatal return. The corpus thus maps a trajectory from neurotic symptom to archetypal enactment, with ideology, mythology, and clinical observation in perpetual tension.
