New York ? Even if teachers are allowed to discuss human sexuality in health class, they might want to think twice about including a drawing lesson.

An unnamed man won’t be teaching in Yonkers anymore after he asked his seventh-grade students to draw some genitalia on the blackboard. He’s been barred from classes and Superintendent Bernard Pierorazio will ask trustees to fire him.

Yonkers schools spokeswoman Jerilynne Fierstein admits the state’s curriculum calls for the anatomy lessons but “as a teacher you have to be sensitive and you have to look at the age-appropriateness of any activity that you ask a child to do. And this was just not appropriate.”
