IMPOTENCY: CAN. 1068
Sterility renders marriage neither invalid nor illicit. This is the impediment of impotency, set up by natural law.
So one can have a "strictly unitive" and non-procreational marriage if one of the spouses is naturally sterile? I guess because God made them sterile it is different than people making other people sterile, because of the dangers of the injustice of enuch slavery in society.
The couple gives the gift of proper conjugal act as part of matrimony, which is part of proper consent. If that cannot be done, then it is an impediment of divine law. The conjugal act makes them one in flesh.
Can. 1061 §1. A valid marriage between the baptized is called ratum tantum if it has not been consummated; it is called ratum et consummatum if the spouses have performed between themselves in a human fashion a conjugal act which is suitable in itself for the procreation of offspring, to which marriage is ordered by its nature and by which the spouses become one flesh.
