What does the Church teach about Mary's Perpetual Virginity?

I have heard the topic of Mary’s perpetual virginity discussed in great detail on the Q&A program.

As a Catholic, I agree 100% on this teaching. However, I am curious about what it would imply if, as many argue, Mary was not a virgin after Christ’s birth. How would this impact what the Church teaches and what kind of repercussions would this have in God’s divine plan?

The following links should help you better understand the teaching on Mary’s perpetual virginity. If you have any further questions, please contact Catholic Answers directly.
