I add that because, since straight couples are still far more numerous than "gay" ones, I am fairly sure that there's more straight sodomy than gay sodomy. Hate to bring it up, it's so repellent; but I wouldn't want to mislead heterosexuals into thinking that anything they wanna do with their spouse is, by the mere fact that they are "Mr. and Mrs.", rightly ordered.
It's all the more powerful because of its rarity.
