=A Word of Caution=

Let it be repeated that sex instruction should be undertaken with great
tact and thoughtfulness. The one who gives the instruction--whether
parent or teacher--should post himself thoroughly and he should be
practical, go slow, not forcing the lad's development by unnecessary
knowledge, avoiding gush and sentiment. He should not seek confession or
allow the boy to confess to him, for confession will raise a barrier
between the two later on; he should help the boy without invading the
lad's innermost life, his soul; he should learn that there are recesses
in the boy's self that are his own and that bear no invasion, and he
should respect this right of privacy.
