The woman is only sexual, the man is also sexual: this distinction is of considerable importance, as well in space as in time.

La femme est sexuelle seulement, l’homme est aussi sexuel : cette distinction est d’une portée considérable, aussi bien dans l’espace que dans le temps.

Otto Weininger, Sexe et Caractère (1903) (Editions l’age d’homme). Trad. D. Renaud. Editions l’age d’homme. Lausanne, 1975, p. 89

Disclaimer : The works of Weininger are to read knowing the terrible destcruction power they supported, after his own death, against Jewish People, and against Women in general. His texts are sources to understand the common roots between antismetism and antifeminism.
