EXPLANATION OF THE MANIFEST PREPONDERANCE OF SEXUAL PERVERSIONS IN THE
PSYCHONEUROSES

The sexuality of psychoneurotics has perhaps been placed in a false
light by the above discussions. It appears that the sexual behavior of
the psychoneurotic approaches in predisposition to the pervert and
deviates by just so much from the normal. Nevertheless, it is very
possible that the constitutional disposition of these patients besides
containing an immense amount of sexual repression and a predominant
force of sexual impulse also possesses an unusual tendency to
perversions in the broadest sense. However, an examination of milder
cases shows that the last assumption is not an absolute requisite, or at
least that in pronouncing judgment on the morbid effects one ought to
discount the effect of one of the factors. In most psychoneurotics the
disease first appears after puberty following the demands of the normal
sexual life. Against these the repression above all directs itself. Or
the disease comes on later, owing to the fact that the libido is unable
to attain normal sexual gratification. In both cases the libido behaves
like a stream the principal bed of which is dammed; it fills the
collateral roads which until now perhaps have been empty. Thus the
manifestly great (though to be sure negative) tendency to perversion in
psychoneurotics may be collaterally conditioned; at any rate, it is
certainly collaterally increased. The fact of the matter is that the
sexual repression has to be added as an inner factor to such external
ones as restriction of freedom, inaccessibility to the normal sexual
