Monogamy, however, is a serious danger to the well-being of society, according to Ehrenfels. Not only does a monogamous society morally and legally sanction (Ehrenfels 1907, 78), even “sanctify” (Ehrenfels 1907, 81), female possessiveness and jealousy, by establishing an unnatural and merely culturally justified exclusive right on the father of her children (Ehrenfels 1907, 79), but also thereby engenders all kinds of sexual corruption and general degenerations. By enforcing an unnatural sexual morality, it leads to double standards (Dickinson 2002, 259), where men are driven by their sexuality to prostitutes, pornophilia and hyperaesthesia. Due to the demand their appetites generate, men who buy sexual satisfaction are complicit in the human trade and the corruption of young women who enter into prostitution, though it would go too far to forbid prostitution altogether (Ehrenfels 1907, 62). The natural sex drive of men, which cannot be satisfied through monogamy, drifts into extremes, both toward pornophilia (“die Freude am Schweinischen”), i.e., pure sensualistic, even animalistic stimulation, disregarding the function of reproduction, through masturbation or in brothels (with all the risks of STDs), and in the other direction toward incessant search for variety and exotic eroticisms (Ehrenfels 1907, 49).
