Abstract
The article describes and analyzes some of the tension involved in the implementation of sexual education in Catholic schools in the city of La Plata, within the framework of the obligation to implement an educational policy with a gender perspective, such as the National Program of Comprehensive Sexual Education (ESI, according to its Spanish initials), which the Catholic Church and in particular the La Plata Archbishopric openly oppose. In this case, the paper explores the “cultural limits” that hinder the full implementation of this policy, with emphasis on the structure of subjective feelings that underlie the practices of teachers and school principals.
