(_b_) As fear in the newly married. Young women who remain anesthetic during the first cohabitation not seldom merge into an anxiety neurosis which disappears after the anesthesia is displaced by the normal sensation. As most young women remain undisturbed through such a beginning anesthesia, the production of this fear requires determinants which I will mention; (_c_) As fear in women whose husbands suffer from ejaculatio precox or from diminished potency; and, (_d_) In those whose husbands practice coitus interruptus or reservatus. These cases go together, for on analyzing a large number of examples one can easily be convinced that they only depend on whether the woman attained gratification during coitus or not. In the latter case one finds the determinant for the origin of anxiety neurosis. On the other hand the woman is spared from the neurosis if the husband afflicted by ejaculatio precox can repeat the congress with better results immediately thereafter. The congressus reservatus by means of the condom is not injurious to the woman if she is quickly excited and the husband is very potent; in other cases the noxiousness of this kind of preventive measure is not inferior to the others. Coitus interruptus is almost regularly injurious; but for the woman it is injurious only if the husband practices it regardlessly, that is, if he interrupt coitus as soon as he comes near ejaculating without concerning himself about the determination of the excitement of his wife. On the other hand if the husband waits until his wife is gratified, the coitus has the same significance for the latter as a normal one; but then the husband becomes afflicted with an anxiety neurosis. I have collected and analyzed a number of cases which furnished the material for the above statements. (_e_) As fear in widows and intentional abstainers, not seldom in typical combination with obsessions; and, (_f_) As fear in the climacterium during the last marked enhancement of the sexual desire. The cases (_c_), (_d_), and (_e_), contain the determinants under which the anxiety neurosis originates in the female sex, most frequently and most independently, of hereditary predisposition. I will endeavor to demonstrate in these—curable, acquired—cases of anxiety neurosis that the discovered sexual injuries really represent the etiological moments of the neurosis. But before proceeding I will mention the sexual determinants of anxiety neurosis in men. I would like to formulate the following groups, every one of which finds its analogy in women: (_a_) Fear of the intentional abstainers; this is frequently combined with symptoms of defense (obsessions, hysteria). The motives which are decisive for intentional abstinence carry along with them the fact that a number of hereditarily burdened eccentrics, etc., belong to this category.
