Hi!
The vagina expands and contracts to permit such things as intercourse and childbirth.
So, I would answer the question--NO.
Obviously when a 10 lb baby is born, the vagina shrinks again afterwards.
The opening or introitus is usually changed somewhat by intercourse ( eg the hymen) and by childbirth. There is at least one doctor that recommends laser vaginoplasty, although the American College of OB/gyn discredits him.
Good luck!

Sure it does, the vagina is just getting bigger!
