A good article Corneus.
I recall reading an article, a few years ago, about the origins of the external 'vibrator'.
It told of Woman who were experiencing menopause, being declared 'insane' (for lack of knowledge of this phenomena) and locked up in 'Mad-Houses', also referred to as 'Lunatic Asylums'.... these poor Women were totally misunderstood, and without hormonal treatment being available would be virtually 'climbing up the wall' within their 'cells'!
A doctor discovered that if they were given an orgasm then they would quieten down for a few days.
So succesful was this methodology that it became widely practiced in Mental Asylums across the Western World... and was applied as a 'medication' on a daily basis.
The 'downside' was that carers were experiencing repetative strain injury from digitally stimulating female clitoris... all day long.
Herald the electric vibrator... which relieved the staff from using their fingers... and proved to be a 'God-send'.
Modern medicine of course now treats menopause with HRT and Menopausal Women are no longer declared 'insane' but instead are simply treated with HRT.
Seems this wonder drug (HRT) has deprived what modern man would call a 'plumb' job !
