The sexual complex occupies a pivotal position in the depth-psychological literature as the site where instinctual life, social prohibition, and psychic structure collide to produce pathology. Freud established the foundational claim: sexuality, innate to the human organism, is rendered socially incompatible and thus repressed, generating a nucleus around which related traumas coalesce into neurosis. Murray Stein's exposition of this Freudian architecture makes explicit that it is not social conflict per se but the moral self-contradiction of a psyche simultaneously driven to deny and affirm itself that renders the sexual complex pathogenic. Jung, working from word-association experiments, both borrowed and contested this framework: his early clinical cases demonstrate how the sexual complex manifests through disturbed reaction-times, dream sequences, and somatic symptomatology, and how it can displace or mask other complexes (the school-complex giving way to the sexual complex at puberty). Yet Jung's theoretical development moved decisively against the Freudian reduction of all complex structures to sexuality, arguing that sexual libido is one tributary of a broader psychic energy rather than the singular root of psychic life. This tension — between a sexuality that generates the paradigmatic complex and a psychology that refuses to make it foundational — defines the central theoretical fault-line through which figures from Bleuler to Rank, and from Abraham to Hillman, navigate their competing accounts of desire, repression, and psychic organisation.
Sexuality, which is built into the innate make-up of the human being, becomes socially incompatible and is therefore split off from consciousness and repressed. This creates a sexual complex around which related traumas cluster.
Stein articulates the Freudian mechanism by which repressed sexuality crystallises into a sexual complex serving as a nucleus for the accumulation of associated traumas.

It is therefore not surprising if the school-complex is replaced by the sexual complex, though only outwardly; as we have seen, it is still present in the associations, it is still an open wound which is above all sustained by self-reproaches.
Jung demonstrates clinically that the sexual complex can functionally displace an antecedent complex (the school-complex) at puberty while the original wound persists beneath the substitution.

There are signs that allow the conclusion that she pays more than usual attention to her genitals... Masturbation is one of the most frequent sources of self-reproach and self-criticism. This complex, or, better, this aspect of the sexual complex, is also indicated by the following associations.
Jung identifies masturbation guilt as one specific aspect of the sexual complex, traceable through word-association data to constellations of self-reproach and shame.

Perhaps one may express the hypothesis that the first analysis stimulated the patient's sexual complex, so that her own person appeared in the next dream.
Jung hypothesises that analytic intervention can activate a latent sexual complex, causing the patient's self-representation to emerge within subsequent dream material.

The reduction of a complex structure to sexuality is a valid causal explanation only if it is agreed beforehand that we are interested in explaining solely the function of the sexual components in complex structures.
Jung argues that reducing complex psychic structures to sexuality is a circular, partial explanation that cannot stand as a general psychological theory.

The complex does not belong entirely to the hierarchy of ideas contained in ego-consciousness; because of its strong emotional charge it is more or less autonomous and forces the association in its direction.
Jung establishes the general autonomy of the complex — directly applicable to the sexual complex — as a function of its affective charge overriding conscious associative control.

The nuclear element automatically creates a complex to the degree that it is affectively toned and possesses energic value... It produces a specific constellation of psychic contents, thus giving rise to the complex.
Jung's structural account of complex-formation — via an affectively charged nuclear element — provides the theoretical mechanism underlying the sexual complex's capacity to organise related psychic contents.

From this broad viewpoint, sexual libido is but one branch of the more general Will or life force... at some stages of human development, both collective and individual, sexual libido is more prominent and fundamental; at others, it is less so.
Stein articulates Jung's revisionary libido theory, which repositions the sexual complex within a broader energic framework rather than as the singular foundation of psychic life.

Such a development reveals the complex in its original strength, which, as I said, sometimes exceeds even that of the ego-complex. Only then can one understand that the ego had every reason for practising the magic of names on complexes.
Jung describes how any complex, including the sexual complex, can exceed the ego-complex in strength, producing neurotic dissociation when it can no longer be circumvented.

Both sexes become neurotic, when they wish to gratify the primal libido for the mother, as compensation for the birth trauma, not by means of the sexual gratification designed for them, but by means of the original form of infantile gratification.
Rank reframes the sexual complex's pathogenic force as a failed substitution for the birth trauma's primal longing, relocating the etiological ground from Oedipal sexuality to pre-natal fixation.

Sexuality appears as a god of fertility, as a fiercely sensual, feminine daemon, as the devil himself with Dionysian goat's legs and obscene gestures, or as a terrifying serpent that squeezes its victims to death.
Jung illustrates how sexuality, when constellated as a complex charged with physiological affect, becomes anthropomorphised into mythological imagery reflecting its autonomous, daemonic character.

Psychological childhood has been examined enough through the sexual and nutritive instincts. But the creative, too, must have a genetic aspect.
Hillman implicitly critiques the hegemony of the sexual complex in developmental depth psychology, calling for an archetypal account of childhood that privileges creative wounding over sexual and nutritive reduction.

Unlike Freud, we cannot identify sexuality with the very principle of the tendencies in the individuated being; the being also cannot be divided into two principles, that of pleasure and that of the death drives.
Simondon, from a philosophical-ontological standpoint, refuses to ground the complex structure of the individuated being in sexuality as its primary organising principle, paralleling Jung's theoretical objection.
