You have a cramped view of how the Holy Spirit speaks. Sodomy is about 45 minutes out of any gay couple's week, like any marriage. You can have an opinion of sodomy v. copulation, it is not helpful in settling the question of whether gays are created that way or chose it. Sadly, I doubt you care. Your issue is public morality, not personal happiness, and not for their benefit (if you cared, you would honor their testimony) but the fleeting authority of the Magisterium in such issues.
