You said, “Excuse me, but god supposedly designed things so that there can never be any virgin mothers.” I am contradicting that statement.

He used God with a lower case “g” I think you know where he stands. Recommend you don’t waste your time.
As all Christians know from the evidence of Scriptures Mary was a virgin upon conceiving Jesus Christ by the Holy Spirit with the overshadowing Power of The Most High. And we know Joseph was commanded to not have relations with her until the birth of Christ.
