Our decadent youth: 1904

The boy of the present generation has more practical knowledge of sexual instinct at the age of fifteen than, under proper training, he should be entitled to at the time of his marriage; and the boy of eleven or twelve boastfully announces to his companions the evidences of his approaching virility. Nourished by languishing glances and fanned by more intimate association on the journey to and from school, fed by stolen interviews and openly arranged festivities, stimulated by the prurient gossip of the newspaper and the flash novel, the gallant of twelve years is the libertine of fourteen.

--From Sexology--

Hopefully with the oft predicted death of newspapers and books, this problem can finally be solved.
