“What is the Church’s position on sex education?” Liahona, March 2017
Church leaders have said that you should be taught about intimacy primarily by your parents. In this responsibility, parents are encouraged to teach in the home about sexual intimacy honestly and plainly to help their children avoid serious transgressions. The Church even has materials to help in this teaching.
When it comes to what you are taught in school about sex, Church leaders have urged your parents to be aware of what is taught there and to do what they can to ensure that it follows good moral and ethical values.
