語源 1

From Middle English sexe (“gender”), from Old French sexe (“genitals; gender”), from Latin sexus (“gender; gender traits; males または females; genitals”), from Proto-Italic *seksus, from Proto-Indo-European *séksus, from *sek- (“to cut, cut off, sever”), thus meaning "section, division" (into male かつ female).

Usage for women influenced by Middle French le sexe (“women”) (attested in 1580). Usage for third and additional sexes calqued from French troisième sexe, referring to masculine women in 1817 and homosexuals in 1847. First used by Lord Byron and others in English in reference to Catholic clergy. Usage for sexual intercourse first attested in 1900 (in the writings of H.G. Wells).
