"Normal conjugal intercourse fully asserts masculinity and femininity. The man asserts himself as man and husband, and the woman equally asserts herself as woman and wife. In contraceptive intercourse, only a maimed sexuality is asserted. In the truest sense sexuality is not asserted at all. Contraception represents such a refusal to let oneself be [known]] that it simply is not real carnal knowledge. A deep human truth underlies the theological and juridic principle that contraceptive sex does not consummate marriage. Contraceptive intercourse, then, is not real sexual intercourse at all. By it the spouses simply do not become "one flesh" (Gen 2: 24). That is why the disjunctives offered by this whole matter are insufficiently expressed by saying that if intercourse is contraceptive, then it is merely hedonistic. This may or may not be true. What is true - at a much deeper level - is that if intercourse is contraceptive, then it is not sexual. In contraception there is an "intercourse" of sensation, but no real sexual knowledge or sexual love, no true sexual revelation of self or sexual communication of self or sexual gift of self. The choice of contraception is in fact the rejection of sexuality. The warping of the sexual instinct from which modern society seems to suffer is not so much an excess of sex, as a lack of true human sexuality."
