I think mary banged her brother or father and got pregnant. Imagine being a bastard of incest in those days. Definitely no right of inheritance, no not a candidate for marriage. No marriage = no sex, according to the customs. Probably pretty harshly persecuted. That's maybe why hung out with the whores?
Matthew 19
10 The disciples said to him, “If such is the case of a man with his wife, it is better not to marry.” 11 But he said to them, “Not everyone can receive this saying, but only those to whom it is given. 12 For there are eunuchs who have been so from birth, and there are eunuchs who have been made eunuchs by men, and there are eunuchs who have made themselves eunuchs for the sake of the kingdom of heaven. Let the one who is able to receive this receive it.”
Let the Children Come to Me
13 Then children were brought to him that he might lay his hands on them and pray. The disciples rebuked the people, 14 but Jesus said, “Let the little children come to me and do not hinder them, for to such belongs the kingdom of heaven.” 15 And he laid his hands on them and went away.
