=Physiological Necessities.= There is another reason, a physiological reason, for the great importance which men and women attach to the feminine fetishes. More sexual excitement and a greater muscular tension are necessary in the male than in the female at the time of the sexual union. The female, being physiologically submissive, can wait for her desire to grow under the influence of the male's caresses. The male, on the contrary, has to be aggressive and cannot fulfill his biological part unless his desire has been aroused by other sensations than that of the sexual union. Hence the greater expenditure of time and effort on the part of the female to make herself attractive to the male. Hence also the long drawn courtship of flirtation thru which the female of every animal species endeavors to bring the male to the highest possible point of sexual excitement before surrendering herself to him. =Foot and Shoe Fetishism= is more complicated. The mother's feet are the part of her body which the infant, crawling on the floor or attempting to walk, beholds most frequently and at the closest range. That variety of fetish, however, should not be as strong as other fetishes more directly related to the child's nutrition, comfort and safety. When shoe fetishism become compulsive, it is a neurosis due to the repression of some erotic desire aroused in childhood by some striking incident. One case cited by Freud, illustrates that process. "A man to whom the various sex attractions of woman now mean nothing, who in fact, can only be aroused sexually by the sight of a shoe on a foot of a certain form, is able to recall an experience he had in his sixth year and which proved decisive for the fixation of his libido. One day he sat on a stool beside his governess. She was a shriveled old maid who, that day, on account of some accident, had put a velvet slipper on her foot and stretched it out on a foot stool. "After a diffident attempt at normal sexual activity, undertaken at the time of his puberty, a thin, sinewy foot like that of his governess, had become the sole object of his desires. The man was carried away irresistibly if other features, reminiscent of his governess, appeared in conjunction with the foot. Through this fixation, the man did not become neurotic but perverse, a foot fetishist, as we say." I wish to call the reader's attention to the expression "after a diffident attempt at normal sexual expression." It indicates a feeling of inferiority, likely to cause failure and also increased by failure which is always in evidence in every neurotic and which drives him toward easier goals, along the line of least effort.
