"Copulation is uterine regression. 'The purpose of the sex act can be none other than an attempt to return to the womb.' 'The sex act achieves this transitory regression in a three-fold manner: the whole organism attains this goal by purely hallucinatory means, somewhat as in sleep; the penis, with which the organism as a whole has identified itself, attains it partially or symbolically; while only the sexual secretion itself possesses the prerogative, as representative of the ego and its narcissistic double, the genital, of attaining
in reality to the womb of the mother.' "
