Quote 19
As soon as he touched her she seemed to wince and stiffen. To embrace her was like embracing a jointed wooden image. And what was strange was that even when she was clasping him against her he had the feeling that she was simultaneously pushing him away with all her strength. The rigidity of her muscles managed to convey that impression. She would lie there with shut eyes, neither resisting nor co-operating but submitting. It was extraordinarily embarrassing, and, after a while, horrible. But even then he could have borne living with her if it had been agreed that they should remain celibate. But curiously enough it was Katharine who refused this. They must, she said, produce a child if they could. So the performance continued to happen, once a week quite regularly, whenever it was not impossible. She even used to remind him of it in the morning, as something which had to be done that evening and which must not be forgotten. She had two names for it. One was "making a baby," and the other was "our duty to the Party." (1.6.13)
Winston hated having sex with Katharine because of her mindless devotion to the Party.
Quote 20
Winston sighed inaudibly. He picked up his pen again and wrote:
She threw herself down on the bed, and at once, without any kind of preliminary in the most coarse, horrible way you can imagine, pulled up her skirt. (1.6.14-15, Winston)
How romantic.
Quote 21
Then the memory of her face came back, and with it a raging, intolerable desire to be alone […]. At the sight of the words I love you the desire to stay alive had welled up in him, and the taking of minor risks suddenly seemed stupid. It was not till twenty-three hours, when he was home and in bed – in the darkness, where you were safe even from the telescreen so long as you kept silent – that he was able to think continuously. (2.1.20)
Flustered by the note and Julia’s interest in him, Winston feels alive again, no longer hampered by the sexual repression that restricted him earlier.
