His wife, with all that entails.
God told Joseph to marry Mary.
God on marriage:
The husband should fulfill his marital duty to his wife, and likewise the wife to her husband. The wife's body does not belong to her alone but also to her husband. [note: Mary and Joseph would not go against God's plan for marriage] In the same way, the husband's body does not belong to him alone but also to his wife. Do not deprive each other except by mutual consent and for a time, so that you may devote yourselves to prayer. Then come together again so that Satan will not tempt you because of your lack of self-control.--1 Corinthians 7:3-5Joseph and Mary knew this and lived their lives as a normal married couple.
Later so called "Church Fathers" made the claims that Mary was conceived without sin, lived a sinless life, remained a perpetual virgin.
Those attributes of course could only be attributed to God, in this case Jesus. (Of course it was only His body that was conceived, He was "from the beginning.") Could NOT possibly be attributes of Mary.
It usually 'entails' SEXUAL INTERCOURSE.
