Later in the 20th century, Austrian Freudo-Marxist Wilhelm Reich, who coined the term "sexual revolution" in one of his books from the 1940s, became a consistent propagandist for sexual freedom, going as far as opening free sex-counseling clinics in Vienna for working-class patients (Sex-Pol stood for the German Society of Proletarian Sexual Politics). According to Elizabeth Danto, Reich offered a mixture of "psychoanalytic counseling, Marxist advice and contraceptives" and "argued for sexual expressiveness for all, including the young and the unmarried, with a permissiveness that unsettled both the political left and the psychoanalysts." The clinics were immediately overcrowded by people seeking help. During the early 1970s, the English anarchist and pacifist Alex Comfort achieved international celebrity for writing the sex manuals "The Joy of Sex" and "More Joy of Sex".
