Because His Church teaches it (prohibition of contraception) and has since the begining.

Could you provide a link to a document please? Second century, or before, and not just quoting a saint, or referring to abortion or withdrawal, or simple misogyny?
I am a bit confused by what you are asking, are you expecting say Clement in his writings say “Oh yes, No Condoms and watch out for the pill, trust me on this guys…”
The Church’s stance has always been all marital acts must be open to the possibility of life
“on account of their prominent ancestry and great property, the so-called faithful [certain Christian women who had affairs with male servants] want no children from slaves or lowborn commoners, [so] they use drugs of sterility or bind themselves tightly in order to expel a fetus which has already been engendered” (Refutation of All Heresies 9:12). -Hippolytus of Rome 255 A.D.
“Why do you sow where the field is eager to destroy the fruit, where there are medicines of sterility , where there is murder before birth? You do not even let a harlot remain only a harlot, but you make her a murderess as well. . . . Indeed, it is something worse than murder, and I do not know what to call it; for she does not kill what is formed but prevents its formation. What then? Do you condemn the gift of God and fight with his laws? . . . Yet such turpitude . . . the matter still seems indifferent to many men–even to many men having wives. In this indifference of the married men there is greater evil filth; for then poisons are prepared, not against the womb of a prostitute, but against your injured wife. Against her are these innumerable tricks” ~ John Chrysostom 391 A.D. (Homilies on the Romans)
