development, which normally proceed in close relation to each other.
The girl should be informed how to care for her health. The boy
should be instructed about the sex life of the opposite sex to know
what they have a right to expect, or rather what they have no right
to demand of the other. Boys during the adolescent period, which has
been called the "age of chivalry and romance," are keen to

is at this time that we are to appeal to their sense of honor in
establishing ideals of purity, and the sense of responsibility as
bearers of the life stream. The standards of sex morals are
established during this period, for girls as well as for boys. Their
strength to time of temptation will lie in the ideals which now
become fixed. We want our girls to grow up demanding purity of the
young men they will meet, not pretending that they do not know the
difference. And we want our boys to grow up with faith in the
literal truth of that fine line about Sir Galahad:

His strength is as the strength of ten, because his heart is pure.
