passionately and the mocking bird gurgles provokingly, when the robin
fills its scarlet breast and the starling floats in ecstasy through
the perfumed air, when the pigeon coyly woos its mate, and the
butterfly flirts with the dazzling multicolors of its wings, when
all the marvelous devices of sex attraction in nature, selection and
courting, mating and reproducing are pondered, who but must wonder at
the infinite possibilities of reaction of the sex hormones? All is for
love, and all is because of the love in the blood that is manufactured
unconsciously by a few hidden cells.

EXPRESSIONISM AND EXHIBITIONISM

We need a detailed examination of the various forms of expression
art has differentiated into, in its relation to exhibitionism and as
effects of the circulating libido-producing substance of the gonads.
Sex exhibition differs in man and woman because of the differently
combined internal secretions that are their substrates. The male's
attitude, aggressive pursuit, is instigated by the compound adrenal
and gonad endocrines. The female's various emulsions of coyness and
display are motivated by posterior pituitary and gonad hormones in
alliance.

It is a dogma to state that the internal secretions of sex do not
begin to function until after puberty. Some children manifest
exhibitionism with a certain independence of environment.
Before adolescence a good many girls act like tom-boys, and are
distinguishable externally from boys only by their clothes. But others
display signs of sex differentiation that are to be traced back to
an awakening interstitial gonad action. Some boys have no interest
whatever in sex. Others will show an intense curiosity spontaneously,
a curiosity which perhaps may be explained as a larval precocity,
dependent upon the minimum of sex hormone production by the gonads.
Close observation of the correlation of somatic and psychic
development in extreme examples of these children corroborates this
view. Jonathan Hutchinson has described full-busted children of
London already boasting of their affairs. Indeed, as education and
environment affect the body (in so far as they influence it as a
whole) by exciting or inhibiting the glands of internal secretion,
sex-arousing stimuli from without must be considered to evoke their
effects as stimulants of the latent puberty glands.

At puberty, when the sex glands bloom, and the complex of the sex
instincts is activated, exhibitionism
