Sexual maturity occupies a structurally pivotal position in the depth-psychological corpus, functioning simultaneously as a developmental milestone, a normative ideal, and an analytic problem. Freud's foundational treatment in the Three Essays on the Theory of Sexuality (1905) establishes the template: sexual maturity is not a sudden biological event but the culmination of a diphasic developmental process, reaching its decisive resolution at puberty when component instincts must achieve genital synthesis. For Freud, the entire edifice of neurosis rests upon failures, fixations, and regressions along this developmental arc. Jung complicates the picture by insisting that psychological puberty frequently outlasts biological puberty, and that genuine maturity of judgment in men may lag years behind that of women — a claim grounded not in biology but in the psyche's differential readiness. Masters (2012) radicalises the concept by arguing that sexual maturity is irreducibly multi-dimensional: intellectual, emotional, moral, psychological, and spiritual development must converge before genuine sexual maturity is achievable. Panksepp's affective neuroscience grounds the question neuroendocrinologically, tracing how puberty reorganises hypothalamic circuits whose organisational effects were laid down prenatally. Across these traditions, a persistent tension runs between biological and psychological definitions of maturity, and between developmental telos and the recognition that most persons remain, in significant respects, sexually immature.
You cannot have sexual maturity without a corresponding emotional, moral, mental, psychological, and spiritual maturity.
Masters argues that sexual maturity is irreducibly holistic, requiring the simultaneous development of emotional, moral, intellectual, and spiritual dimensions rather than any single register alone.

precocious sexual maturity and also because, by spoiling the child, it makes him incapable in later life of temporarily doing without love or of being content with a smaller amount of it.
Freud identifies precocious sexual maturity as a pathogenic factor that predisposes the child to neurosis by disrupting the developmental economy of libidinal frustration and satisfaction.

The first of these begins between the ages of two and five, and is brought to a halt or to a retreat by the latency period... The second wave sets in with puberty and determines the final outcome of sexual life.
Freud's diphasic model of object-choice frames sexual maturity as the resolution of a two-stage developmental process in which puberty determines the final organisation of sexuality.

The third phase is the adult period from puberty on, and may be called the period of maturity.
Jung demarcates a tripartite developmental schema in which the adult period commencing at puberty constitutes the phase of maturity, distinguishing it from presexual and prepubertal stages.

a girl of twenty is usually older than a man of twenty-five, as far as maturity of judgment is concerned. With many men of twenty-five the period of psychological puberty is not yet over.
Jung dissociates psychological from biological maturity, arguing that men frequently remain in the illusion-laden period of psychological puberty well into their mid-twenties.

What does actually awake in them at this period is the reproductive function, which then makes use for its own purposes of material lying to hand in body and mind.
Freud distinguishes sexuality from reproduction, clarifying that puberty activates the reproductive function which recruits pre-existing psychical and somatic material rather than creating sexuality ex nihilo.

Freud invokes anatomical evidence from Lipschiitz to ground the concept of sexual maturation biologically, linking the interstitial sex-gland hypothesis to the notion of a sexual latency period preceding full maturation.

Following puberty, these organizational effects in the POA influence male sexual tendencies in all mammals that have been carefully studied.
Panksepp grounds sexual maturity neuroendocrinologically, demonstrating that puberty activates preoptic area circuits whose organisational parameters were established earlier by prenatal testosterone exposure.

The intensification of the brake upon sexuality brought about by pubertal repression in women serves as a stimulus to the libido in men and causes an increase of its activity.
Freud analyses the gendered asymmetry of pubertal repression, arguing that inhibition of female sexuality at maturity dynamically intensifies male libidinal pressure.

the onset of his illness is precipitated when, either as a result of his own progressive maturity or of the external circumstances of his life, he finds himself faced by the demands of a real sexual situation.
Freud identifies progressive sexual maturity as a precipitating factor in neurotic breakdown when libidinal development has been arrested and the demands of adult sexuality can no longer be avoided.

every juncture in this involved combination can be an occasion for a dissociation of the sexual instinct, as we have already shown from numerous instances.
Freud enumerates the constitutional and environmental factors that interfere with normal sexual development toward maturity, establishing the theoretical basis for diverse pathological outcomes.

Unable to attain the highest pleasure through a full masculine activity, they have turned to what is to them the most intense pleasure—to the passive one of allowing bodily products to flow out.
Abraham interprets ejaculatio praecox as evidence of arrested libidinal development, the failure to attain full sexual maturity expressed as regression to a passive-oral mode of satisfaction.

Triumph belongs to this attainment of maturity by growth process. Triumph does not belong to the false maturity based on a facile impersonation of an adult.
Winnicott distinguishes authentic developmental maturity achieved through growth from a premature pseudo-maturity that forecloses the creative immaturity of adolescence.

Often enough the first impulses after puberty go astray, though without any permanent harm resulting.
Freud acknowledges the normative fumbling of early post-pubertal sexuality, framing adolescent sexual misdirection as a transitional phenomenon in the consolidation of mature object-choice.

It is generally assumed that libido in this sense comes into existence only at puberty. How, then, are we to explain the fact that children have a polymorphous-perverse sexuality?
Jung interrogates the Freudian equation of libido with pubescent sexuality by posing the problem of infantile polymorphous sexuality, which predates the conventional onset of sexual maturity.

Sexuality previously centered in the genitalia begins to radiate through the entire body. Microcosm begins to reflect macrocosm.
Woodman describes a post-individuation expansion of sexuality beyond its genitally localised form, implying that psycho-spiritual development reconfigures the bodily expression of mature sexuality.
