marriage-and-friendship

Shouldn't we at least be asking whether the transcending of venereal desire that marriage requires of a mostly or entirely 'heterosexual' man who marries for the sake of love, friendship, and raising a family isn't more or less the same as the transcendence required of a man whose venereal desire is 'oriented' mostly or entirely toward men but who restrains these drives, and who marries for the sake of love, friendship and raising a family? Of course, men with little venereal desire for women can't proceed towards marriage driven by such desire. For them, marriage must develop from friendship. But wouldn't it be better if all marriages developed from friendship?
