e same caused uncontrollable sexual
excitement; the nates also exerted a great attraction. The alvine
excreta exerted this influence even in the absence of the woman;
it was, however, necessary that she should be a sexually
desirable person. The perversion in this case was not complete;
that is to say, that the excitement produced by the act of
defecation or the excretion itself was not actually preferred to
coitus; the sexual idea was normal coitus in the normal manner,
but preceded by the visual and olfactory enjoyment of the
exciting fetich. When coitus was not possible the enjoyment of
the fetich was accompanied by masturbation (as in the analogous
case of urolagnia in a woman summarized on p. 62.) On one
occasion he was discovered by a friend in a bedroom belonging to
a woman, engaged in the act of masturbation over a vessel
containing the desired fetich. In an agony of shame he begged the
mercy of silence concerning this episode, at the same time
revealing his life-history. He has constantly been haunted by the
dread of detection, as well as by remorse and the consciousness
of degradation, also by the fear that his unconquerable obsession
may lead him to the asylum.

The scatalogic groups of sexual perversions, urolagnia and coprolagnia, as
may be sufficiently seen in this brief summary, are not merely olfactory
fetiches. They are, in a larger proportion of cases, dynamic symbols, a
preoccupation with physiological acts which, by associations of contiguity
and still more of resemblance, have gained the virtue of stimulating in
slight cases, and replacing in more extreme cases, the normal
preoccupation with the central physiological act itself. We have seen that
there are various considerations which amply suffice to furnish a basis
for such associations. And when we reflect that in the popular mind, and
to some extent in actual fact, the sexual act itself is, like urination
and defecation, an excretory act, we can understand that the true
excretory acts may easily become symbols of the pseudo-excretory act. It
is, indeed, in the muscular release of accumulated pressures and tensions,
involved by the act of liberating the stored-up excretion, that we have
the closest simulacrum of the tumescence and detumescence of the sexual
process.[32]

In this way the erotic symbolism of urolagnia and coprolagnia is
completely analogous with that dyna
