It's an utter lie from top to bottom if it doesn't have one pyramid for what men require from women and what women require from men. If your marriage is between two "spouses" you're gay married even if technically one of you is male and the other female.
Non gay marriage wedding vows sum it up: Woman: promises to "love, honor, and obey" Man: promises to "love, comfort, and protect" Nearly zero non-gay marriages have been performed in the last 40 years. (purely coincidentally, fertility has fallen off a cliff)
