ΠαράθεσηThe morphological isolation of the sexual area from the rest of the body in the case of man, may be taken as symbolical of the relation of sex to his whole nature. Just as there is a contrast between the sexual and the sexless parts of a man's body, so there is a time-change in his sexuality. The female is always sexual, the male is sexual only intermittently. The sexual instinct is always active in woman (as to the apparent exceptions to this sexuality of women, I shall have to speak later on), whilst in man it is at rest from time to time. And thus it happens that the sexual impulse of the male is eruptive in character and so appears stronger. The real difference between the sexes is that in the male the desire is periodical, in the female continuous.
This exclusive and persisting sexuality of the female has important physical and psychical consequences. As the sexuality of the male is an adjunct to his life, it is possible for him to keep it in the physiological background, and out of his consciousness. And so a man can lay aside his sexuality and not have to reckon with it. A woman has not her sexuality limited to periods of time, nor to localised organs. And so it happens that a man can know about his sexuality, whilst a woman is unconscious of it and can in all good faith deny it, because she is nothing but sexuality, because she is sexuality itself.
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.
