“It is a terrible error to let any natural impulse, physical or mental, stagnate. Crush it out, if you will, and be done with it; or fulfil it, and get it out of the system; but do not allow it to remain there and putrefy. The suppression of the normal sex instinct, for example, is responsible for a thousand ills. In Puritan countries one inevitably finds a morbid preoccupation with sex coupled with every form of perversion and degeneracy.”
