“In view of the close links between the sexual dimension of the person and his or her ethical values, education must bring the children to a knowledge of and respect for the moral norms as the necessary and highly valuable guarantee for responsible personal growth in human sexuality. For this reason, the Church is firmly opposed to an often widespread form of imparting sex information dissociated from moral principles. That would merely be an introduction to the experience of pleasure and a stimulus leading to the loss of serenity—while still in the years of innocence—by opening the way to vice.” ― Pope St. John Paul II, Familiaris Consortio
