Mrs. X. visited me professionally; aged 28; mother of three children; been married nine years; spare, dark hair and eyes, rather brilliant; small of stature; retiring and confiding of disposition. She was very neurasthenic and excitable; never hysterical; bowels constipated. I prescribed all kinds of treatment for her during the first six weeks, after which time, as I had failed to find out anything that might be a cause for such a peculiar nervousness, I suggested an examination _per vaginam_. As soon as my finger reached the orifice of the vagina, I was convinced that my case was a sexual one, as a nervous, passionate shiver ran over her; but she soon controlled herself, and I proceeded with my examination, with the discovery of only slight general irritation. She then gave me the following account of her married life and condition. She was married at nineteen, a robust, vigorous girl. Her husband was amorous and ignorant of her requirements; would soon satisfy his desires and go to sleep, when she had but just become excited; but when her erotic excitement was aroused she had no control of it: would remain wakeful during the entire night, with the husband sleeping, regardless of her condition. She finally learned to use a clothes-pin, by which means she could appease her burning and bring about an orgasm. She says that she could then sleep. She of late had consented to the advancements of a prominent lawyer; but she was conscience-stricken and desired, if possible, to be a “good woman;” but was satisfied that, to be a virtuous woman, she must remain away from her husband, so that her passion never would be beyond her control. I immediately, after her departure, sent for the husband, and informed him how to perform the marital connection, and that, if he desired that his wife should become a well woman, he must adhere to my instructions. He was glad of the information, and was successful in his efforts. She was soon free from her troublesome neurasthenia, and beatitude prevails to this day; and, I believe, she is as virtuous and worthy a woman as a man deserves.
