The objective of this document is to understand that sexuality is an integral part of people's lives (in their different stages or ages, and in all their diversity), and that it contributes to the development of their identity and, therefore, to their development Social. It is about capacities rather than content, which must be developed in an interdisciplinary way and progressively so that people act responsibly towards themselves and with others. The document explains that the education of sexuality is closely related to understanding, reflection and discernment, and strengthens the bases for lifelong learning, preparing young people for adult life. Thus, the focus is on achieving sustainable human development and well-being.
