"Charity is the form of all the virtues. Under its influence, chastity appears as a school of the gift of self. Self-mastery is ordered to the gift of self."
"Caritas est omnium virtutum forma. Sub eius influxu, castitas tamquam schola apparet doni personae. Dominium sui ad sui ordinatur donum."
Catechism of the Catholic Church #2346.
Conversely, then, no chastity (theologally informed), no gift of self.
