That’s not what Catholics or orthodoxes believe and considering it’s hard to find a take on Christianity that isn’t held by any Protestant group I’m not likely to believe any of them as the word on Christianity.

Catholic doctrine is that Mary was a virgin who today we would consider a child/adolescent who was married but not consummated with a laborer descendant of David. She was asked by an Angel to bear Jesus and accepted without hesitation. And she remained a virgin until she ascended to heaven body and soul at the end of her life.
