In his next contribution _Sadger_ reports the results of the analysis of an invert during a period of six months (_Zur Ætiologie der konträren Sexualempfindung_, Med. Klinik, 1909, No. 2). The special preference of his patient for passive pederasty he traces to the frequent use of enemas during childhood. (In fact it seems to me that the many unnecessary enemas administered during early childhood may contribute towards the fixation of the anus as an erogenous zone.) He also traces out in this case the repressed heterosexuality. “The vacillations of the _libido_ between male and female are like the facial innervation which, as is well known, is based on the equilibrium between the muscles innervated simultaneously by the pair of _facialis_ nerves. Paralysis of the _facialis_ nerve on one side causes not only weakness of the muscles on the affected side but induces also contractures of the muscles on the opposite side.” The patient referred to was attached exclusively to his father, who, himself somewhat homosexually inclined, won the child’s heart through his excessive tenderness, in contrast to the rather severe mother. During his fourth year, on account of the mother’s pregnant state, he slept with his father, an occurrence to which _Sadger_ attaches great significance. The objects of the boy’s homosexual attachments bore some resemblance to the beloved sister. He weaned himself away from his attachment to his mother during his fifteenth year, when he saw his mother deformed with a tremendous ascites on account of which she had to be tapped a number of times. Her appearance at the time filled him with disgust for all women. As over-determination of this feeling-attitude of aversion he recalls the following: after the puerperium referred to above his mother had a profuse leucorrheal discharge which the boy, already sensitive to all scents—he was four years of age at the time—found very repulsive whenever he approached his mother. The subject also recalls vividly how his mother repulsed his aggressive ways with her, between his 3rd and 6th year. (“He always wanted to grab her by the breasts and tried to go to her room and to the bathroom as soon as she went in.”) Much as physicians unacquainted with infantile sexuality may ignore such aggressions they do take place and some mothers have verified them for me. On the other hand it is hardly likely that a child four years of age should be repelled from the mother on account of scent. At that early age scent is rather a stimulant and is never accompanied by disgust. I turn now to the last and most comprehensive deductions formulated by _Sadger_ in his study entitled: _Ein Fall von multipler perversion mit hysterischen Absenzen_ (‘A case of multiple perversions with hysterical amnesias’).[9]
