Its focus is on values clarification and deciding whether or not to have sexual intercourse. Sex education courses often deal exclusively with the biological aspects of reproduction.
Adolescence is a time of social and emotional change as well as physical change.

Physical maturity happens quite naturally. Therefore, it seems imperative that sex education in the schools include values clarification and decision making related to sexual activity.
