sadists should be shunned. Unfortunately the fact that a man is a 

sadist is often not found out until after marriage, but as soon as the 

wife has found it out she should leave the man and demand a divorce. 

Sadism is a sufficient ground for a separation or divorce. No person 

with any moral feeling in him or her should be responsible for 

bringing children into the world with a possible sadistic heredity. 

Sadistic cruelty is often of the gross, brutal, repulsive kind, but 

sometimes the sadist inflicts on his "beloved" object refined tortures 

of which only a cunning "demon" is capable. The sufferings which the 

wives of some sadists have to undergo are known only to themselves and 

to a few--very few--physicians. 

=Masochism= 

Masochism is a sexual perversion in which the person, man or woman, 

_likes_ to suffer pain, beatings, insults and other cruelties at the 

hands of the beloved object. It is a dysgenic factor but much less 

important than sadism. 

=Sexual Impotence= 

Sexual impotence is not hereditary, but impotence in the male either 

so complete that he cannot perform the act or consisting only in 

premature ejaculations (relative impotence or sexual insufficiency) 

should constitute a bar to marriage. This impotence may not interfere 

with impregnation; the wife may have children and the children will 

not be in any way defective, but the wife herself, unless she is 

completely frigid, will suffer the tortures of hell, and may quickly 

become a sexual neurasthenic, a nervous wreck, or she may even develop 

a psychosis. Any man suffering with impotence should have himself 

treated before marriage until he is cured; if his impotence is 

incurable, then for his own sake and for the sake of the girl or woman 

he is supposed to love he should give up the idea of marriage. The 

only permissible exception is in cases in which the prospective wife 

knows the nature of her prospective husband's trouble, and claims that 

she does not care for gross sexual relations and therefore does not 

mind the impotence. In case the wife is absolutely _frigid_, the 

marriage may turn out satisfactory. But I would always have my 

misgivings, and should the wife's apparently absent but in reality 

only dormant libido suddenly awaken there would be trouble for both 

husband and wife. It is therefore necessary to emphasize: in all cases 

of impotence--caution! 

=Frigidity= 

Frigidity, as we have explained in a previous chapter, is a term 

applied to lack of sexual desire or sexual enjoyment in women. Of 

course many women before marriage are themselves ignorant of their 

sexual condition. Having learned to restrain their impulses, to 

repress any sexual stir, they themselves are often unable to say
