es, Stanley Hall states that "Dr. F.N.
Seerley, who has examined over 2000 normal young men as well as
many young women, tells me that in his opinion individual
variations in these parts are much greater even than those of
face and form, and that the range of adult and apparently normal
size and proportion, as well as function, and of both the age and
order of development, not only of each of the several parts
themselves, but of all their immediate annexes, and in females as
well as males, is far greater than has been recognized by any
writer. This fact is the basis of the anxieties and fears of
morphological abnormality so frequent during adolescence." (G.S.
Hall, _Adolescence_, vol. i, p. 414).

In accordance with the supreme importance of the part they play, and the
intimately psychic nature of that part, the sexual organs, both internal
and external, are very richly supplied with nerves. While the internal
organs are very abundantly furnished with sympathetic nerves and ganglia,
the external organs show the highest possible degree of specialization of
the various peripheral nervous devices which the organism has developed
for receiving, accumulating, and transmitting stimuli to the brain.[77]

"The number of conducting cords which attach the genitals to the
nervous centers is simply enormous," writes Bryan Robinson; "the
pudic nerve is composed of nearly all the third sacral and
branches from the second and fourth sacral. As one examines this
nerve he is forced to the conclusion that it is an enormous
supply for a small organ. The periphery of the pudic nerve
spreads itself like a fan over the genitals." The lesser sciatic
nerve supplies only one muscle--the gluteus maximus--and then
sends the large pudendal branch to the side of the penis, and
hence the friction of coitus induces active contraction of the
gluteus maximus, "the main muscle of coition." The large pudic
and the pudendal constitute the main supply of the external
genitals. In women the pudic nerve is equally large, but the
pudendal much smaller, possibly, Bryan Robinson suggests, because
women take a less active part in coitus. The nerve supply of the
clitoris, however, is three or four times as large as that of the
penis in proportion to size. (F.B. Robinson, "The Intimate
Nervous Connection of the Genito-Urinary Organs With the
