In the 18th and 19th centuries, some European theologians and physicians described it as "heinous", "deplorable", and "hideous", but during the 20th century these taboos generally declined.
18. ja 19. sajandil kirjeldasid mõned Euroopa teoloogid ja arstid seda kui "hirmuäratavat", "kahetsusväärset" ja "koledat" akti, kuid 20. sajandil need tabud üldjuhul langesid.
