In an exercise of questioning the offi cial history of Mayan sexualities in the Southeast of Mexico, especially the Yucatan Peninsula, this article seeks to deepen, reclaim, and re-signify the sex-generic constructions that the Maya have been developing since the pre-Hispanic era. Mayan sex-generic constructions form part of a cosmology and religiosity that sees both the feminine and the masculine as necessary and complementary elements to archive cosmic balance. This worldview not only generated less unequal societies, as demonstrated through the outstanding role of women and non-binary people in Mayan society, but it also resisted, with its respective transformations, centuries of Spanish conquest and colonisation. From this perspective, the diversity of sexualities observed among Mayan peoples today cannot be conceived as a product of Western modernity, but instead as a remnant with roots embedded in more ancient times. The article argues that, to start from Mayan sex-generic constructions for the study of contemporary sexualities requires generating radical dialogues and alliances on equal terms with peoples on whom the colonial hetero-patriarchal binary was imposed, as well as with Western emancipatory processes like Queer Theory.
