The Holy See adopted the latter position. The former, which won out in the final Platform, was championed by countries like the United States and Canada and by the European Union. It was reflected in the almost obsessive attention the document paid to sex and reproduction. Another difference between the Holy See and its opponents regarding sexuality is even more profound. Essentially, Catholic teaching sees human sexuality as inherently relational.
Sexual relations are acts which affect couples, families, and eventually communities.
Furthermore, sexual relations deeply affect each individual actor. They can uplift and can degrade us. Opponents of this vision see sex as a matter of individual preference, having primarily physical effects - satisfaction, pregnancy, or disease. There is no recognition of relational responsibility, only rights to ensure that sex is consensual and that no woman gets a disease or a baby she doesn't want. The second paints a vision of dignified women, created in God's image and meriting worldly recognition of this.
