Other than the Physical Jerks, the sex instinct was another area of human life that the Party sought to kill and use to have full control over the Party members (members?). In Oceania, only the "proles ", the so-called lower class people who did not actually qualify to belong to the Party, were acknowledged to have sexual instincts. Among Party members all love and eroticism was removed from the sex act. Marriages were permitted, but they had to be officially approved and were to be undertaken for the sole purpose of begetting children who would grow up to be responsible Party members. "All marriages between Party members had to be approved by a committee permission was always refused if the couple gave the impression of being physically attracted to each other (57). " Ideally the Party would prefer complete celibacy, which would mean that men and women would forge fewer bonds of individual loyalties and children could be produced artificially. Failing this,  it tried to present the sex act as a rather disgusting preliminary necessity. "Sexual intercourse was to be looked on as a slightly disgusting minor operation, like having an enema.(69) To most of the party members, the sex act would be taken as fulfilling their duty to the Party rather than as their enjoyment (96). By controlling the members' sex instinct, the Party has also forged fewer bonds of individual loyalties and trust. As a result "No one dares trust a wife, a child or a friend any longer (220). This is also evidences of how the party has successfully brainwashed their members.

             The party members are not only controlled physically by Big Brother, but also considered as mentally. To induce (or access) the maximum controls on the members, the party has limited the members' thoughts by inventing the Thought Police (though crime) and brainwashing them. As one of the three main slogans in 1984 "Big Brother is watching you ", all the members are being watched everyday by the Thought Police through the telescreens.
