A man for my MOH. Whats it called and what is your personal opinion?

Hey all, I don't post much so I am coming out from the shadows for this one! I want to have a Matron of Honor and also a 'Man of honor'. Yes, both, because I could never choose between the two! Is there a name for my guy bridesman? And what do you think of this idea? My fiancee (Mark) isn't very happy about it Oh well, oh well! I'm doing it anyway! Have any of you used a man for your MOH or had two MOH? Fedback and opinions are appreciated, as I am wondering why they think this is so outrageous.

Thanks in Advance!
Jackie
