318 may be acts quite analogous to acts indulged in by individuals in perverse satisfaction of the instinct, but who, at the same time, have a natural inclination toward persons of the opposite sex.

Owing to the circumstance that abnormally increased sexuality is almost a regular accompaniment of contrary sexual feeling, acts of lustful cruelty in the satisfaction of libido are easily possible. A remarkable example of this is the case of Zastrow (Casper-Liman, 7. Auflage, Bd. i, p. 190; ii, p. 487), who bit one of his victims (a boy), tore his prepuce, slit the anus, and strangled the child.

Similar sadistic feelings of this kind, in those afflicted with contrary sexual instinct, are found in some of the foregoing histories (comp. Cases 107 and 108 of this edition, and Case 96 of the sixth edition). But masochism also occurs (comp. Case 43, sixth edition; Cases 111 and 114 of this edition; and Case 3, in the first edition of “Neue Forschungen”).
