What God can do is not what God does. God has never forced a virgin to carry His Child, but who would be such a fool to withhold her consent to such a great grace?
Mary, for instance, knew that all generations would call her blessed. She saw God's Child as her blessing, the hope of her people; and she was not alone in that belief.
Have you ever read Luke 2:29-32? "Lord, now you let your servant depart in peace; Your word has been fulfilled: my own eyes have see the salvation you have prepared in the sight of every people: a light to reveal you to the nations and the glory of your people Israel."
My guess is that you can't because all the virgins tell you no and, without consent, you'll end up as some large man's love toy in prison.
