"Then Joseph, being aroused from sleep, did as the angel of the Lord commanded him and took to him his wife, and did not know her till (emphasis added) she had brought forth her firstborn Son.fn And he called His name JESUS." Matthew 1:24-25
Also, the RCC Catechism teaches:
(1601) The matrimonial covenant, by which a man and a woman establish between themselves a partnership of the whole of life, is by its nature ordered toward the good of the spouses and the procreation and education of offspring; this covenant between baptized persons has been raised by Christ the Lord to the dignity of a sacrament.
(1620) Both the sacrament of Matrimony and virginity for the Kingdom of God come from the Lord himself. It is he who gives them meaning and grants them the grace which is indispensable for living them out in conformity with his will. Esteem of virginity for the sake of the kingdom and the Christian understanding of marriage are inseparable, and they reinforce each other:
Whoever denigrates marriage also diminishes the glory of virginity. Whoever praises it makes virginity more admirable and resplendent. What appears good only in comparison with evil would not be truly good. The most excellent good is something even better than what is admitted to be good.
(1640) Thus the marriage bond has been established by God himself in such a way that a marriage concluded and consummated between baptized persons can never be dissolved. This bond, which results from the free human act of the spouses and their consummation of the marriage, is a reality, henceforth irrevocable, and gives rise to a covenant guaranteed by God's fidelity. The Church does not have the power to contravene this disposition of divine wisdom.
(2335) Each of the two sexes is an image of the power and tenderness of God, with equal dignity though in a different way. The union of man and woman in marriage is a way of imitating in the flesh the Creator's generosity and fecundity: "Therefore a man leaves his father and his mother and cleaves to his wife, and they become one flesh." All human generations proceed from this union.
So, was Mary married to Joseph as the Scriptures and the RCC teach, or is she a perpetual virgin as the RCC teaches?
Therefore JOSEPH was perpetually FRUSTRATED!
Mary; I know it's been at LEAST 12 years now that you've had that headache...
