羞恥　男女が体の違いを全裸になって学習する質の高い授業を実践する共学高校の保健体育 (2016)

It is important to give sex education to adolescents. Education by showing books and videos is too indirect and inefficient. At our school, we actually use the body and genitals of the students to teach the difference between the body of men and women. We may actually have sexual intercourse with our students to teach them how to make the right children, but we would like to thank our parents for their understanding and cooperation.
