Answer by Pseudodionysius
Those who engage in sexual intercourse for purposes of pleasure need not be doing so selfishly. If the desire for sexual pleasure motivates one to seek to have sexual intercourse with one's spouse, and if one is also striving to help one's spouse achieve what is good also, one is acting morally and bringing about what is good. For instance, one may succeed in making one's spouse feel loved, or the mutual pleasure may foster intimacy and bonding or comfort may be given and received. Here we see the unitive meaning of sexual intercourse being preserved without the procreative meaning being violated.
John Paul II teaches that far from fostering sensuality, the proper practice of NFP will enhance the loving relationship of the spouses and make their acts of sexual intercourse ones more expressive of love and acts more authentically expressive of total self-giving. The use of NFP, far from bringing about a state of sensuality, is more likely to assist one in gaining control of one's sexual appetites, in appreciating the deeper meanings of sexual intercourse and in being better able to express them. Throughout his writings, John Paul II speaks to this point. Consider this passage:
If conjugal chastity (and chastity in general) is manifested at first as the capacity to resist the concupiscence of the flesh, it later gradually reveals itself as a singular capacity to perceive, love and practice those meanings of the "language of the body" which remain altogether unknown to concupiscence itself and which progressively enrich the marital dialogue of the couple, purifying it, deepening it, and at the same time simplifying it. Therefore, that asceticism of continence, of which the encyclical speaks (HV 12), does not impoverish "affective manifestations," but rather makes them spiritually more intense and enriches.
Those who have the virtue of self-mastery are better able to ensure that their acts of sexual intercourse are more truly acts of love-making rather than acts designed merely to satisfy sexual urges.
