The degree of onanistic satyriasis and of nymphomania depends on the power the venereal sense has over the will. These affections do not exist in those with whom it is optional whether they shall indulge in onanism or not, nor in those who can refrain from coition. Thus, then, a person may masturbate, without being affected with satyriasis. This is the case, when the sentiment of self-preservation is sufficiently strong to resist desires, when the persons yield readily to reprimands and punishments. Satyriasis may be considered as existing to some extent in the onanist, if he cannot refrain. This was the case with a young man, whose history is given by Begin and Fournier. From early puberty, he was addicted to masturbation; and when eighteen years old, he presented some of the bad effects of this habit. This young man was endowed with a brilliant mind: but, although well educated, and although he well knew the dangers of his habit, yet he could not refrain. His good resolutions were formed only to be broken. He died. In a young woman whom we attended, the struggle with her passions terminated more favorably. It was not the desire of preserving her life, which induced her to leave off her bad habits; but the wish of conforming to the will of her father. Her constitution was already considerably affected, when the cause of it was discovered. The father of this young girl told her how much pain and shame her bad habit caused him, and requested her to abstain from it. She was extremely mild and docile, and made every effort to please and obey him. It was in vain: but whenever she was inclined to masturbate, the fault was confessed as soon as committed. Coercive measures were finally resolved upon. The patient not only consented to have her hands tied every night, but requested it, and even stated the manner in which she might be most effectually prevented from abusing herself. The venereal sense gradually became subdued, and confined within the proper limits. And thus, this habit--or, rather, the nymphomania, which was the result, and also the cause of it--was cured.
