On one occasion the patient, already much to be pitied on account of his disease, had the misfortune to contract syphilis. In reply to the question as to what he regarded as the most lustful act, the patient said: “_It is my greatest delight to lie naked on the floor and have myself trod upon by girls wearing elegant boots_; but, of course, this is possible only in brothels.” Moreover, according to the patient’s statements, these sexual perversions of men are well known in many houses of prostitution,—a proof that these are not so very infrequent. The prostitutes call these men “boot-lovers.” But the patient has only very infrequently had the lustful act actually performed, notwithstanding the fact that it is most beautiful and pleasant to him. The patient has no thoughts that impel to intercourse; at least, not in the sense of immissio penis in vagina,—an act that affords him no pleasure whatever. Indeed, he has gradually developed a fear of coitus, which may be sufficiently explained by his numerous unsuccessful attempts; for the patient says himself that his inability to complete coitus embarrassed him exceedingly. The patient has never practiced real onanism. With the exception of a few occasions on which the patient satisfied his sexual desire by onanism with boots or in a similar way, he is innocent of such satisfaction; for, in the excitement with boots, there is scarcely ever anything more than erection; at most, only a slight discharge of fluid takes place slowly, which the patient takes to be semen. Simply a shoe, worn by no one, excites him when he sees it, but not nearly as intensely as when it is worn by a woman. New shoes that have not been worn excite him much less than those that have been used; but they must be free from wear and look as new as possible. Shoes of this kind excite him the most. As has been said, ladies’ boots excite him when they are not on the feet. Under such circumstances, in fancy, L. creates a lady for them; he presses them to his lips and on his penis. He would “die with delight” if a proud, respectable lady were to tread upon him with her shoes.
