Both sexes usually reach physical maturity during adolescence. Late-maturing boys are at a distinct disadvantage in secondary school. Because of the emphasis in our culture on physical prowess, they may be unable to compete. The sensitive teacher helps such boys excel in other areas-academics, music, drama, student government, etc. Girls reach puberty around age twelve, two years earlier than boys.
Boys reach the peak of their sexual drive at age nineteen, girls much later.

The teacher cannot ignore, punish, tease, or force a child to deal with his fears. They are best handled when the teacher holds the child securely and explains the situation, then arranges for the child to have a good experience in facing that fear. The teacher's non-fearful behavior is critical.
