It is a terrible error to let any natural impulse physical or mental stagnate. Crush it out, if you will, and be one with it; or fulfill 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.
