My working theory is that the Shire is the only part of middle earth where hereronormativity is the default.
That's why the Kingdom of Men ended up with so many rings of power, he originally offered two to the Commune of Women but they politely refused because accepting expensive jewelery from a creepy older man would set a bad example to the children.
Meanwhile the men thought anything that made other men kneel before them would result in a happy ending.
While the Hobbits were getting The One Ring to Mt. Doom the women were oblivious to the sausage fest and busy upgrading their gloworm trail.
