The virtue to which we are called with regard to sexual relationships is called chastity. Therefore, through integrity and self control, the chaste person observes the true meaning and intimacy of sexual relations as God intended. Pornography is sinful and offensive because it perverts the conjugal act: the intimate giving of spouses to each other in physical and spiritual union. It also does grievous injury to the dignity and character of both, those who participate in making it and those who view it.
Pornography does nothing but foster in a person the fallen inclination to treat others as things for their own sexual gratification. Anyone who views or uses pornography incapacitates themselves to love properly; they cannot enjoy a healthy, pure relationship with a member of the opposite sex, nor can they hope to enter marriage honestly, fruitfully, and faithfully. One might even go are far as saying that those who use pornography, at least in the case of men, have actually emasculated themselves from what it means to be a man of God.
