Psychopathia sexualis: With especial reference to contrary sexual instinct

4. Neuroses (hysteria, neurasthenia, epileptoid states, etc.) co-exist.

Almost always the existence of temporary or lasting neurasthenia may be proved. As a rule, this is constitutional, having its root in congenital conditions. It is awakened and maintained by masturbation or enforced abstinence. In male individuals, owing to these practices or to congenital disposition, there is finally neurasthenia sexualis, which manifests itself essentially in irritable weakness of the ejaculation centre. Thus it is explained that, in most of the cases, simply embracing and kissing, or even only the sight of the loved person, induce the act of ejaculation. Frequently this is accompanied by an abnormally powerful feeling of lustful pleasure, which may be so intense as to suggest a feeling of magnetic currents passing through the body.
