Tele, that was avery lucid and excellent post. I have to partly disagree with Daegus on the matter of whether or not the question is relevant precisely for the reasons Tele mentions, though I think the rest of his post was sound. I know that, when my fiancée and I are both in a car, whether it is hers or mine, I always drive and we would both find it unnatural if the opposite were the case. I mentioned in the Multiracial thread that, in Québec as late as the 1970s, a man would be ridiculed by other men as a fif/moumoune ("homo/fag") if he were in the passenger seat while his wife or girlfriend was driving. I think the sentiment is based on an appreciation of a fundamental truth : the man is naturally designed to assume the patriarchal position as director and guide of those under his care and authority, the women of his family. Imagine if, in the old days, the women held the reins and whipped the horse while their husbands/fathers and sons/brothers were sitting peacefully behind them in the wagon talking. The image is absurd and offensive to the sensus catholicus; it opposes the intuitive grasp we have of the natural order. Now imagine if a painter were to convey a scene of St Joseph sitting on a donkey while the expectant Virgin Mother led on foot to Bethlehem -- he would rightly be condemned as deranged and impious. That being said, the question is not one of sin as such but of virtue and what consists with the natural way of things.
