Remember that when Uzzah merely touched the Ark of the Covenant to steady it, he died. Even a man motivated by his marital duty would not have relations with the new Ark of the Covenant . . . how could you enter where God had been? That doesn't make sense either.
The Bible does not directly deny that Mary remained a virgin, and the traditions of the Church Fathers to the earliest days explicitly state that she did. Many of the Church Fathers knew Mary and the Apostles personally. Where the Bible is silent there is no reason even for one who believes in Sola Scriptura to ignore contemporary witness outside the Bible.
Are you saying that no one ever touched Jesus? He was after all God.
Why could someone touch Jesus but not where Jesus had been? That doesn’t make sense.
They died when they touched the Ark of the Covenant because God told them NOT to touch it. They were to carry it with poles.
There are types and shadow of lots of things in the OT. That does not mean that things happen exactly the same.
Surely you can provide a list of those that knew Mary personally, that lived to write about her...
