Sexuality was not often discussed by classical anarchists, but the few that did felt that an anarchist society would lead to sexuality naturally developing. However, sexual violence was a concern for anarchists such as Benjamin Tucker, who opposed age of consent laws, believing they would benefit predatory men. A historical current that arose and flourished during 1890 and 1920 within anarchism was free love. In contemporary anarchism, this current survives as a tendency to support polyamory and queer anarchism. Free love advocates were against marriage, which they saw as a way of men imposing authority over women, largely because marriage law greatly favoured the power of men. The notion of free love was much broader and included a critique of the established order that limited women's sexual freedom and pleasure. Those free love movements contributed to the establishment of communal houses, where large groups of travelers, anarchists and other activists slept in beds together. Free love had roots both in Europe and the United States. However, some anarchists struggled with the jealousy that arose from free love. Anarchist feminists were advocates of free love, against marriage, pro-choice (utilising a contemporary term) and had a similar agenda. Anarchist and non-anarchist feminists differed on suffrage, but they were nonetheless supportive of one another.
