The popular theory of the sexual impulse corresponds closely to the
poetic fable of dividing the person into two halves--man and woman--who
strive to become reunited through love. It is therefore very surprising
to hear that there are men for whom the sexual object is not woman but

_persons_ are called contrary sexuals, or better, inverts; the
_condition_, that of inversion. The number of such individuals is
considerable though difficult of accurate determination.[3]

*The Behavior of Inverts.*--The above-mentioned persons behave in many
ways quite differently.

(_a_) They are absolutely inverted; _i.e._, their sexual object must be
always of the same sex, while the opposite sex can never be to them an
object of sexual longing, but leaves them indifferent or may even evoke
sexual repugnance. As men they are unable, on account of this
repugnance, to perform the normal sexual act or miss all pleasure in its
performance.

(_b_) They are amphigenously inverted (psychosexually hermaphroditic);
_i.e._, their sexual object may belong indifferently to either the same

(_c_) They are occasionally inverted; _i.e._, under certain external
conditions, chief among which are the inaccessibility of the normal
sexual object and initiation, they are able to take as the sexual
