Mary remained a virgin in order to provide an incontrovertible evidence of the miraculous nature of the birth of Christ, and, quite simply, because her intimacy with God made sex superfluous. She did not abstain from sex on the false notion that it would have been a sin for her.

Book, chapter, and verse please.

Even if the scenario you posit was true and it may have been superfluous for her, what about Joseph? Her having sex wasn't all about her and her needs.

She would also be disobeying God's command to be fruitful and multiply.

Chapter and verse for what? What I say is common sense.

it may have been superfluous for her, what about Joseph? Her having sex wasn't all about her and her needs

What goes for Mary, goes for Joseph too. He is her husband; whqt they do, or rather don't do, they do together.

She would also be disobeying God's command to be fruitful and multiply

Riiight. Christ alone kinda feels not fruitful enough.
