Bare in mind this is french but has been handily translated for your needs.
The Fatal Consequences of Masturbation: a cautionary, illustrated page from a mid-19th-century French book with no name. It describes in vivid detail the woes and tormet that may beset the wandering lonley palm of a 17 yr old boy. What it says about 20/21 yr olds isnt mentioned so i assume we’re all safe now boys (and maybe girls ).
