If anything, an impotent man who gets married but is willing to procreate if a miracle occurs is much more open to life than a potent man who gets married and willfully refuses to procreate.Because the sexual act is necessary for the Sacrament of Marriage to be true. Sex in marriage is really similar to Communion. In the Sexual act you are worshiping your spouse, in Communion you are worshiping Christ. Just like sex, Communion is not necessary other then once to be a Catholic in full Communion. But just like Communion, we all called to do it as much as possible to keep our bodies from sin. What you are speaking of does happen with religous couples who are part of an order that allows spouses into their ranks.
This is the reason why the Church will not recognize someone who is not able to have sex, but they can be allowed to marry under the Bishops advice I believe. Procreation is not necessary for the Sacrament of Marriage but they must be open to it.
