In the female sex, also, there are persons in whom the sexual life, and especially the sexual impulse, awakens very late. This may happen notwithstanding the fact that menstruation has begun at the normal age. Both the peripheral phenomena of detumescence, and also the phenomena of contrectation, may be thus retarded; and the former especially may permanently fail to appear. We see girls who appear remarkably virtuous, because, while other girls are rejoicing at having found an admirer, they pass coldly along, in the streets and elsewhere, their eyes directed forwards, and rigidly avoid exchanging glances with any male person. Although this delayed sexual development does not arouse in us the same unsympathetic feelings in the case of young women as it does in the case of young men, it is none the less necessary to recognise the phenomenon in the female sex as well, and this not on medical grounds merely, but also on educational, ethical, and social grounds. In fine, in such cases, we have to do with something very different from cases in which from a true sense of shame or on moral grounds a girl maintains her mental and bodily chastity; different, also, from the cases in which we have to do with women whose bodily development is normal, but who in other respects resemble rather the type of those in whom the reproductive glands have been removed. I may take this opportunity of insisting upon the fact that the unduly retarded awakening of the sexual life, or the complete failure of the sexual impulse to appear, is not especially to be desired, and entails dangers and disadvantages just as does a premature development of sexuality. I may recall, in this connexion, certain earlier experiences. At one time it was assumed that there was a mental disorder known as pyromania; the pyromaniac was one with an irresistible impulse to light incendiary fires. To-day, we no longer admit the existence of any such disease, and the impulse to light incendiary fires, when such a morbid impulse manifests itself, is regarded as a symptom of imbecility, of cerebral degeneration, &c. But we may take this opportunity of reminding the reader that Henke,[113] an earlier investigator, regarded pyromania as due chiefly to arrest or disturbance of the physical and psychical phenomena of puberty. Esquirol himself appears to have shared this opinion; and although modern psychiatry takes quite a different view of pyromania, we have none the less to insist that unduly retarded development may, just as much as premature development, give rise to undesirable consequences.
