Stefan Zweig, in the Eros Matutinus chapter of The World of Yesterday https://ia601609.us.archive.org/21/items/in.ernet.dli.2015.1... discusses how porn and prostitutes were peddled in the latter days of the Austro-Hungarian Empire (A.E.I.O.U.).

He even speaks of delaying puberty until after graduate school:

p.71 "Here, too, an inner dishonesty disclosed itself, for the middle-class calendar in no way agreed with that of Nature. As far as society was concerned, a young man did not reach manhood until he had secured a “social position” for himself—that is, hardly before his twenty-fifth or twenty-sixth year. And so there was an artificial interval of six, eight, or ten years between actual manhood and manhood as society accepted it ; and in this interval the young man had to take care of his own “affairs” or adventures."
