Benj. Tarnowsky observed a case of priapism in a soldier which had lasted for over two years and had prevented the patient from absolving his active military service. The complete erection of the organ continually existed in a chronic state and never ceased for a moment. The organ did not wilt even after several coitions, which, in the beginning of his sickness, were tried by the patient in order to free himself from the annoying state of affairs. In the course of his sickness, coition, and especially ejaculation, caused him such violent pains that commixtio was never tried again. Voluptuous thoughts and sexual desire had entirely disappeared. Even the thought of coition caused the patient disagreeable sensations. Priapism, therefore, if it were at all a disease of a sexual nature, would more properly belong among the anomalies of sexual anaesthesia. Satyriasis, on the other hand, is a psycho-sexual anomaly of increased sexual desire. Scarcely has the desire been appeased, when it returns with the same force and vigor as before. The following case may serve as an illustration of such class of cases. Mr. X., a soldier, twenty-three years of age, in prostibulum meretricem visit, qua concubit, pretium usitatum resolvit et relinquit. Scarcely did he reach the door of her room, cum voluptas resurgeret. Itaque revenit, iterum eam comprimit, resolvit et relinquit. This time he managed to descend half the stairs, cum voluptas experrecta esset. Qua re redit, actionem repetit, resolvit et relinquit. But he had no time to come down the stairs, cum concitatus esset. Quo modo sexies ad puellam reveniebat, until he had no more money for her services and had to leave her, but not yet entirely satisfied. Such a case represents a true sexual neurosis of insatiable lust. In the pronounced cases of satyriasis, the individual is the personification of sexuality. In his proximity everything turns upon sex. Nothing is suffered to prevail but sexual emotions. Every glance, motion or word of his has a sex coloring. He is nothing but a demoniac sex-creature. Every word he utters has an obscene emotional tone. His exclamations of surprise, fear, anger, etc., are all borrowed from the realm of sex. He is a screaming vortex of lubescent lubricity. A continual lustful scent exudes from him. He is perennially in quest for sexual gratification. He tries to excite every woman he comes in contact with and is himself excited by her. Moral consideration is an unknown quantity for him. The inhibitions, normally emanating from the cerebral centre, are destroyed in him. He is continually bent on new sensations. This picture of the evil spirit of satyriasis is still surpassed by nymphomania. The woman suffering from nymphomania is more excessive in her demands than the man afflicted with satyriasis.
