I'm afraid that this post comes close to reproducing the myth that the big masturbation scare emerged in Victorian age - which is certainly not the case. Victoria was born in 1819 and became Queen of Great Britain in 1837; to place something that emerged
more than 100 years before Victoria was even born in "the Victorian Age" is just ridiculous - but it's still pretty common to blame all kinds of European sexophobia on the old royal teapot. Not fair :no:
No, we know very well when the big masturbation scare emerged and what kickstarted it: A booklet sold in the London bookmarket in the first quarter of the 18th century - that's in the early Enlightenment period.
The booklet was titled
Onania; or, The Heinous Sin of Self-Pollution and its first edition was probably printed and sold somewhere in the interval 1708-1716. It seems impossible to be more precise since the first edition still existing in British libraries is the 4th.
Anyway! "Onania" became an instant commercial success, getting printed and published in dozens of subsequent new editions and you could still buy a fresh printed copy of this booklet in London in the 1750s.
In 1760 all of Europe got a new authority telling them how dangerous onanism was: This new authority was Swiss, born in Grancy in kanton Vaud, and named S.A.A.D. Tissot (1728-1797), physician and the writer of
L'Onanisme published in 1760.
Oueen Victoria wasn't even born when dr. Tissot passed away in 1797.
