A case example of fetishism from Krafft-Ebing (1887)

Z began to masturbate at the age of 12. From that time he could not see a woman's handkerchief without having orgasm and ejaculation. He was irresistibly compelled to possess himself of it. At that time he was a choir boy and used the handkerchiefs to masturbate within the bell tower close to the choir. But he chose only such handkerchiefs as had black and white borders or violet stripes running through them. At age 15, he had coitus. Later on he married. As a rule, he was potent only when he wound such a handkerchief around his penis. Often he preferred coitus between the thighs of a woman where he had placed a handkerchief. Whenever he espied a handkerchief, he did not rest until he was in possession of it. He always had a number of them in his pockets and around his penis
