Plenty of prominent Churchmen (including some Church Fathers and saints) in Catholic and Protestant history talked about sex (and in some cases women as well) like it was a necessary evil that should only be tolerated for the sake of having children.
As St. Augustine notes, “Intercourse even with one’s legitimate wife is unlawful and wicked where the conception of the offspring is prevented. Onan, the son of Juda, did this and the Lord killed him for it.” 
45. St. August., De coniug. adult., lib. II, n. 12, Gen, XXXVIII, 8-10.
Further, from early in the tradition, a secondary purpose was recognized. St Augustine put it this way:
“Husband and wife owe one another not only the faithful association of sexual union for the sake of getting children—which makes the first society of the human race in this our mortality—but more than that a kind of mutual service of bearing the burden of one another’s weakness, so as to prevent unlawful intercourse. (12)

Reality of truth is what faithful Catholics accept, assent to, and offer.
St. John Chrysostom also affirmed the sacrament of love in marriage and acknowledged the unitive purpose:
“The procreation of children in marriage is the ‘heritage’ and ‘reward’ of the Lord; a blessing of God (cf. Psalm 127:3). It is the natural result of the act of sexual intercourse in marriage, which is a sacred union through which God Himself joins the two together into ‘one flesh’ (Genesis 1-2, Matthew 19, Mark 10, Ephesians 5, et. al.). The procreation of children is not in itself the sole purpose of marriage, but a marriage without the desire for children, and the prayer to God to bear and nurture them, is contrary to the ‘sacrament of love.’” 19

“Pope Sixtus, in the late 1500’s, condemned simultaneously contraception and abortion. The Holy Office under Pope Pius IX (1846-1878) handed down several decisions condemning contraception, noting that the wrongness of contraception is a wrong against human nature. That is, it is not a “situational” wrong, but is a universal wrong against the nature of man, as is abortion and infanticide.

When human beings have sex for pleasure, money, to make someone feel better, etc.; while rejecting the urge to breed, were acting less like animals.
The failure is in acting while deliberately placing a barrier to conception, thus denying the fact that the pleasure is for the purpose of procreation which is not to be thwarted deliberately by a self-imposed barrier.
