Title for a Male FLOTUS

In class, the question was raised about what to call the male spouse of a female president. This Washington Post column by Miss Manners addresses the issue. Apparently,

"If anything is sillier than first lady, it is first husband, unless this is necessary to distinguish him from a marital successor also on the scene. He would be the host, and addressed simply by his name and “Mr.” or another honorific he held, such as general or governor."

Of course, this solution would mean the man's title couldn't become an acronym. Such is life.
