Die Konträre Sexualempfindung (Karl Friedrich Otto Westphal)  

"We owe thanks to Westphal ("Archiv f. Psychiatric," ^ ii., p. 73) for the first systematic consideration of the manifestation in question, which he defined as "congenital reversal of the sexual feeling, with consciousness of the abnormality of the manifestation," and designated with the name, since generally accepted, of antipathic sexual instinct. At the same time, he began a series of cases, which up to this time has numbered about 200, those reported in this monograph not being included."--Psychopathia Sexualis (1886) by Richard Freiherr von Krafft-Ebing
