This reflective piece seeks to show how teachers of English as a Foreign Language (EFL) in primary schools can include a gender perspective as a tool to promote and develop social transformation and reflection when integrating Comprehensive Sexuality Education (CSE) in their lessons using different literary materials. The development of a gender perspective involves a critical examination of power and unequal relations between sexed bodies. In the case of Argentina, the passing of Law 26,150 created a National CSE Program, which enforces the teaching of a responsible sexuality education from a gender and human rights perspective. This article describes some of the literary materials and initiatives that we, two EFL primary level teachers, have designed and implemented for the development of such perspective in our lessons following a critical and dialogical pedagogy. We hope these initiatives can help other EFL teachers carry out similar practices according to their contexts.
