Consummation IS required.
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.
Without consummation, a Catholic marriage is invalid. Therefore any couple who intends to NOT have sex…would be entering into an invalid marriage.
A homosexual couple, by extension, cannot consummate a Catholic marriage and therefore cannot be validly married.
Let’s put this to bed…
