Civil Partnerships: Knight-Knight

When religious civil partnership registrations are finally introduced there will still remain one right that married couples have that civil partners are denied.
The civil partners of male peers or knights do not receive a courtesy title to which the wife of a peer or knight is entitled.
One presumes this holds true for monarchs too; and a queen would not be Queen.
But what would the male partner of a knight be called?
Or the "husband" of a big gay Lord?
May Fagburn most humbly suggest... Ladyboy.
