It may be pointed out here that we are quite justified in speaking of a penis-fetichism and also of a vulva-fetichism. This might be questioned. We are obviously justified in recognizing a fetichism which attaches itself to the pubic hair, or, as in a case with which I am acquainted, to the clitoris, but it may seem that we cannot regard the central sexual organs as symbols of sex, symbols, as it were, of themselves. Properly regarded, however, it is the sexual act rather than the sexual organ which is craved in normal sexual desire; the organ is regarded merely as the means and not as the end. Regarded as a means the organ is indeed an object of desire, but it only becomes a fetich when it arrests and fixes the attention. An attention thus pleasurably fixed, a vulva-fetichism or a penis-fetichism, is within the normal range of sexual emotion (this point has been mentioned in the previous volume when discussing the part played by the primary sexual organs in sexual selection), and in coarse-grained natures of either sex it is a normal allurement in its generalized shape, apart from any attraction to the person to whom the organs belong. In some morbid cases, however, this penis-fetichism may become a fully developed sexual perversion. A typical case of this kind has been recorded by Howard in the United States. Mrs. W., aged 39, was married at 20 to a strong, healthy man, but derived no pleasure from coitus, though she received great pleasure from masturbation practiced immediately after coitus, and nine years after marriage she ceased actual coitus, compelling her husband to adopt mutual masturbation. She would introduce men into the house at all times of the day or night, and after persuading them to expose their persons would retire to her room to masturbate. The same man never aroused desire more than once. This desire became so violent and persistent that she would seek out men in all sorts of public places and, having induced them to expose themselves, rapidly retreat to the nearest convenient spot for self-gratification. She once abstracted a pair of trousers she had seen a man wear and after fondling them experienced the orgasm. Her husband finally left her, after vainly attempting to have her confined in an asylum. She was often arrested for her actions, but through the intervention of friends set free again. She was a highly intelligent woman, and apart from this perversion entirely normal. (W.L. Howard, "Sexual Perversion," _Alienist and Neurologist_, January, 1896.) It is on the existence of a more or less developed penis-fetichism of this kind that the exhibitionist, mostly by an ignorant instinct, relies for the effects he desires to produce.
