The sexual impulse occupies a foundational and contested position throughout the depth-psychology corpus. Freud's foundational formulations in the 'Three Essays on the Theory of Sexuality' and the 'Introductory Lectures' establish it as a composite, developmentally staged force whose component instincts — oral, anal, sadistic, scopophilic — achieve genital organization only through a complex history of fixation, regression, and sublimation. For Freud, the sexual impulse is categorically broader than the genital and reproductive, encompassing every erotogenic zone and affective process. Abraham extends this framework clinically, tracing the transformations of the sexual impulse through neurosis, perversion, and the libidinal arrest characteristic of ejaculatio praecox and allied conditions. Jung diverges decisively: where Freud roots libido in the sexual impulse specifically, Jung re-conceptualizes libido as undifferentiated psychic energy of which sexuality is one developmental branch, a revision that reshapes the entire metapsychological edifice. Rank further complicates matters by arguing that the creative impulse cannot be reduced to sexualized artistic drive. Panksepp, approaching from affective neuroscience, grounds sexual arousal in discrete subcortical systems, lending partial biological corroboration to the instinct concept while bypassing the intrapsychic dynamics that preoccupy the analytic tradition. Across these positions, the sexual impulse functions simultaneously as etiological engine, developmental marker, and transformative force whose fate — whether repressed, sublimated, fixated, or discharged — determines the shape of character and symptom alike.
we consider it possible that single portions of every separate sexual impulse may remain in an early stage of development, although at the same time other portions of it may have reached their final goal.
Freud articulates the concept of fixation as the arrest of constituent portions of the sexual impulse at earlier developmental stages, establishing the theoretical ground for neurotic symptom formation.

the forces destined to retain the sexual instinct upon certain lines are built up in childhood chiefly at the cost of perverse sexual impulses and with the assistance of education. A certain portion of the infantile sexual impulse would seem to evade these uses.
Freud argues that the barriers of shame, disgust, and morality are erected precisely through the transformation of perverse infantile sexual impulses, with a residue that escapes sublimation to persist as direct sexual activity.

One of these kinds of excitation we describe as being specifically sexual
Freud posits a chemically distinct class of somatic excitation that is specifically sexual, grounding the sexual impulse in a frontier concept between the physical and the mental.

this same disposition to perversions of every kind is a general and fundamental human characteristic.
Freud contends that the polymorphously perverse disposition of infancy — the substrate of the sexual impulse — is not aberrant but constitutes the universal foundation of human sexuality.

regression of the libido to the antecedent stage of the sadistic-anal organization is the most conspicuous factor and determines the form taken by the symptoms. The impulse to love must then mask itself under the sadistic impulse.
Freud demonstrates how libidinal regression transforms the sexual impulse into its sadistic counterfeit in obsessional neurosis, with murderous ideation concealing erotic longing.

The most obvious explanation, that this tension arises in some way out of the pleasure itself, is not only extremely improbable in itself but becomes untenable when we consider that in connection with the greatest pleasure of all, that which accompanies the discharge of the sexual products, no tension is produced.
Freud analyzes the paradoxical relationship between sexual tension and pleasure, arguing that they are connected only indirectly, thereby complicating any simple hydraulic model of the sexual impulse.

the patient told me spontaneously that for a long time he had considered these states as a kind of translation of his sexual impulse into a mental form. My investigations fully confirmed this view.
Abraham documents, through clinical analysis, the conversion of the sexual impulse into dissociated hysterical dream-states, demonstrating the impulse's capacity for psychic transformation under repressive conflict.

That which in this period seems masculine to us, regarded from the stand-point of the genital phase, proves to be the expression of an impulse to mastery, which easily passes over into cruelty.
Freud identifies the impulse to mastery as the pre-genital precursor of masculine sexual activity, establishing the developmental continuity between sadism and genital sexuality.

They must serve as paths for the attraction of sexual instinctual forces to aims that are other than sexual
Freud articulates the mechanism of sublimation whereby the pathways of the sexual impulse are redirected toward non-sexual somatic and cultural aims, linking neurosis to normal healthy functioning.

all comparatively intense affective processes, including even terrifying ones, trench upon sexuality — a fact which may incidentally help to explain the pathogenic effect of emotions of that kind.
Freud argues that intense affective arousal of any kind, including fear, can activate the sexual impulse, establishing the broad affective tributaries that feed sexual excitation in children.

sexual libido is but one branch of the more general Will or life force. This general stream of psychic energy has several branches, and in the history of human evolution some of these branches are more prominent than others at certain points.
Stein explicates Jung's decisive revision of Freudian theory, in which the sexual impulse is demoted from primary explanatory principle to one developmental branch of a broader, undifferentiated psychic energy.

in woman sex has not the piercing quality that it has in man. If this man had not felt that something was getting organically wrong in his body, he wouldn't be disturbed, and there would be no motive for bothering about his life.
Jung articulates a gendered asymmetry in the urgency of the sexual impulse, arguing that in men it functions as an inexorable organically-grounded compulsion that motivates psychological reckoning.

Often enough the first impulses after puberty go astray, though without any permanent harm resulting.
Freud notes the normative misdirection of early post-pubertal sexual impulses, contextualizing inversion and perversion as expectable fumbling within the broader diphasic trajectory of object-choice.

Cognitive insights commonly govern sexual behavior less than do the insistent feelings of lust, which diminish only with age, stress, and illness.
Panksepp, from a neuroscientific vantage, underscores the autonomy of the sexual impulse from rational governance, aligning empirically with depth-psychological insistence on the impulse's resistance to conscious control.

Her sexual instinct is less active and her resistance against its impulses greater. We traced this difference in her attitude to the new onset of repression at puberty.
Abraham argues that differential repressive capacity at puberty accounts for gendered differences in the urgency of sexual impulses and in susceptibility to alcoholism as a surrogate discharge.

behind this affection, admiration and respect there lie concealed the old sexual longings of the infantile component instincts which have now become unusable.
Freud argues that the 'affectionate current' of adult life conceals repressed infantile sexual longings, demonstrating the persistence and transformation of the sexual impulse across developmental phases.

it would be a confirmation on their part of a view which is alien to them. For this view of art presupposes a voluntaristic psychology, which in my own case I was only able to reach after passing beyond the libido theory of Freud, and which takes Sydow also far beyond his sexualization of the artistic impulse.
Rank explicitly distances his theory of artistic creation from Freud's reduction of the creative impulse to sexualized libido, arguing that a voluntaristic rather than instinct-based psychology is required.

for each step forward under the urge of compulsion there is a lateral elaboration of dance, of play, of ornamentation — a 'breather,' which delays, heightens tension, and expands imaginative possibility and aesthetic form, making patterns, delightful and devious, cooling the compulsion of inborn release mechanisms
Hillman, in archetypal idiom, depicts the sexual impulse as a compulsive inborn release mechanism that imagination and cultural form elaborate and defer, reframing repression as creative elaboration.

Fantasy leads straight into action only when there is not enough space between idea and impulse, when the inner realm is so cramped that nothing can be contained for long.
Hillman frames the collapse of distance between desire and action — including sexual impulse — as a failure of fantasy's containing function, redefining the problem of impulse as one of imaginative poverty.

It seems as if no one could forget, not merely that they are detestable, but that they are also something monstrous and terrifying; as if they exerted a seductive influence; as if at bottom a secret envy of those who enjoy them had to be strangled
Freud remarks on the cultural and theoretical resistance to acknowledging the full range of the sexual impulse, attributing it partly to a concealed envy of perverse satisfaction.

At its origin it attaches itself to one of the vital somatic functions; it has as yet no sexual object, and is thus auto-erotic; and its sexual aim is dominated by an erotogenic zone.
Freud enumerates the three structural characteristics of infantile sexual manifestation — anaclisis, auto-erotism, and erotogenic zone primacy — as the foundational conditions from which the sexual impulse develops.
