You misunderstand marriage.

The intimate physical union of the man and woman give in marriage is simply the last bond the couple gives to itself.  Whole, heart, soul, body, strength.

Their wills were bonded when they exchanged the vows; their bond was completed at consumption. 

In fact a strong case can be made for an annulment if the consumption occurred with contraception.   A lack of whole gift, totality of gift of self.
