It is impossible for women, because they are only sexual, to recognise their sexuality because recognition of anything requires duality. With man it is not only that he is not merely sexual but, anatomically and physiologically, he can “detach” himself from it. That is why he has the power to enter into whatever sexual relations he desires; if he likes he can limit or increase such relations; he can refuse or assent to them. He can play the part of a Don Juan or a monk. He can assume which he will.

To put it bluntly, man possesses sexual organs; her sexual organs possess woman.

—   Otto Weininger
