I don't have an engagement ring, never wanted one, or a big wedding. It just all seemed like such a waste of money that could be used for for useful things, like, God forbid, a house.
I certainly never equated a ring or wedding to my vagina or uterus.
I'm sorta a package deal, and those two parts are just along for the ride.
You know, I always thought the dumb diamond ring was usually more important to the woman. Partly (maybe mostly) to show to others what a catch she got. Someone who could afford such a thing. I truthfully can't think of another reason.
It feels like men just buy it because the woman expects it, not because he feels he now owns her, or bought her sexual favors.
