Betrothal was the first part of marriage. Remember Joseph was going to divorce Mary when the angel told him to take his WIFE into his home. You ignore that she didn’t say that Joseph and I don’t have sex but that she didn’t have sex with anyone.She was not ‘married’ yet…remember, Jews had at that time (and still do, actually) two stages of this relationship. NOW, a Jewish wedding does both stages at the same time, but when Mary and Joseph were 'betrothed," the first stage (which COULD include sexual intercourse, but often did not, if the woman were too young…) during which the woman lived with her parents while the man took the time to make a home for her—and then the second part, when she left her parent’s home to live with her husband.

You have talked about what can be assumed. If a woman is told before she is married, that she will have a child. A normal reaction is NOT to say I don’t have sex but of course I will have children I am getting married. It is a normal response of a married woman. Especially of that time period and that culture. Mary’s response is strange. You say it is not but you have not put forth a plausible reason why.
