I used to stand aside and let my wife go first to the communion rail out of chivalry, ladies first, open the door for her sort of thing. I no longer do. I now lead her to the communion rail.
A while back after giving it some thought, I noticed the priest always gives communion to the husband first at a Nuptial Mass. I've never asked why that is, but that is reason enough for me to have made the change.
God Bless
