Control of thoughts.
It appears from the experience of many men that strenuous work and play are the only efficient weapons for driving sexual images into the background of the mind. This applies not only to sordid and lewd thoughts of unchaste sexual situations, but also to the mental images that are inevitably associated with the purest affection and which should be trained to obey when calm reason so orders.
The following literature will be especially helpful to young men: W.S. Hall's "Sexual Hygiene for Men," or his "Sexual Knowledge"; Exner's "The Rational Sex Life for Men"; Morrow's "The Young Man's Problem," and "Health and Hygiene of Sex for College Students"; King's "Fight for Character" (Y.M.C.A.); and the chapter on Ethics of Sex in "Sex" by Geddes and Thomson.
