Betty's Definition of Sexual Integrity The Marriage Legislation Amendment Bill 2004 defines marriage as the "union of one man and one woman to the exclusion of all others voluntarily entered into for life". Marriage gives opportunity for a splendour of sex impossible outside it. When all the shared life and the shared love of a man and a woman are poured out into the union of bodies , there is sexual union in it's fullness i.e. sexual integrity. The physical and psychological mechanism in a man and in a woman are so complex, so delicately ordered for the generating of new life, that it would be monstrous to deny that this is what sex is meant for, just as lungs are for breathing and the digestive organs are for nourishment. The fact that people can use sex for sterile purposes does not alter the certainty that child bearing is sex's own purpose and a deep and enduring love its reward.
