The patient, about forty years of age, was suffering from endometritis and came to the office for treatment. At the first touch of the introitus vaginae by the finger, the patient suddenly agitata est. She tightly closed her eyes, the respiration became panting, the abdominal muscles contracted, which made the combined examination impossible, her face became red, her entire body was seized by a convulsive tremor, and her pelvis made omnes motiones commixtionis vehementis. At the end of one or two minutes the paroxysm ended with a deep sigh, and the examination could be continued. The attacks were repeated at the beginning of every treatment, and the same had to be discontinued. Without offending the patient, she was told that she needs a curettage. This advice caused her to stay away from the office. In the pronounced cases of nymphomania, the woman will accept the embraces of any man and will solicit even boys. To him who yields to her wiles she brings misery and calamity. She is an object of attraction and carries ruin in her lap for those who become the slaves of her eroticism. A piece of destructive sexuality dwells in the bosom of these women, something of the Delilah-nature, for all who come in contact with them. They consume men’s strength and vigor physiologically and psychologically. The nymphomaniac woman is not able to free herself from the thraldom of eroticism. Her sexual instinct is irresistible and untamable. Nymphomania leads the sufferer to any degradation, to the practice assidui stupri manu and even to bestiality. Magnan mentions the case of a lady of forty-seven years of age, who from her early childhood manifested excessive voluptas. She was always nervous, eccentric, and of a romantic disposition. When she was only ten years old she began to practice concarnationem. At the age of nineteen she got married, but although her husband was sexually perfectly normal, he could not satisfy her often enough. Qua re jugiter cum aliis viris commiscebatur, and although this infidelity made her entirely unhappy and miserable, she was powerless to overcome her insatiable desires. In another case of Magnan, the patient had a passion for men from her earliest youth. She was of good family, well bred, of pleasant disposition, and exceedingly modest. As a little girl she was the terror of the family. Scarcely was she alone with any male, child or adult, statim aperiebat muliebria et poscebat satisfactionem voluptatis, even going so far as to lay hold of the person. Marriage did not cure her intense desire. She loved her husband passionately, yet indiscriminately petebat placationem voluptatis a quovis viro with whom she happened to be alone, were he her servant, laborer, or even school-boy. This insatiable passion continued to possess her after she had become a grandmother. At the age of sixty-five she was yet recklessly passionate as before.
