Self-pollution

SELF-POLLUTION is that unnatural Practice by which Perſons, of either Sex, may defile their own Bodies without the Aſſiſtance of others, whilſt yielding to filthy Imaginations they endeavour to imitate, and procure to themſelves, that Senſation which God has ordered to attend the carnal Commerce of the two Sexes, for the Continuance of our Species.

The vice consists in any excitement of the genital organs produced otherwise than in the natural way. It is known by the terms, self-pollution, self-abuse, masturbation, onanism, manustupration, voluntary pollution, solitary or secret vice, and other names sufficiently explanatory.
