Sexual Intercourse TrainingIn junior high levels, the selection system for sexual education training becomes required in the upper level school. Sexual intercourse training aims to help students better understand the body of the opposite sex through a curriculum that involves direct intercourse with a well-acquainted classmate, rather than becoming confused by vague descriptions found in sex-ed textbooks. (Sexual intercourse training also prepares students for adulthood, teaching them to make safe decisions when engaging in risky behaviour.)
