Richard von Krafft-Ebing,
Psychopathia Sexualis
(1892)
“ Honored sir, I have a responsible occupation, and I think I can give the assurance that my abnormal inclination has never, even in a hair’s breadth, caused me to deviate from the duty imposed on me. Aside from this abnormality, I am not insane, and I might ultimately become contented; but I have, particularly of late years, suffered too much not to look on the future with painful feeling. For the future will certainly not bring fulfillment of the desire which constantly glows under the ashes,—the desire to possess a lover who understands and returns my love. ”
