As far as the 'who wears a wedding ring' goes
Royalty don;t seem to
My Dad and Granddad never did - my Mum's Dad - dunno but I know he did have a ring - probably a signet ring
I did read somewhere that it is more of a lower class thing - and then families that have a tradition of men wearing rings but are now middle class (or higher) still wear them
I didn;t really want one - but my wife wanted to get me one - so I wear it
lost it a while ago - had to admit it and discovered it some weeks later in the drawer iwth the holiday stuff that hasn;t been used since before the pandemic
weird
still
