In order to put a stop to the declining birthrate, a new sex education called "Home Visit-Type Impregnation Sex Education" is being launched! This is a wonderful sex education where a teacher who specializes in impregnation education at school visits students' homes and gives sex education to the female students themselves and to their families in the case of male students, and continues to visit them until they become pregnant by having unprotected sex on dangerous days! We want to stop the declining birthrate with this sex education!
