Has anyone ever heard of a man wearing an engagment ring?

Hi! I of course got the pretty diamond engagement ring. It makes my fiance feel jelous because we have his band (it's a pretty regular looking titantium band engraved on the inside saying "forever and always" with a cross) and he wants very badly to wear it because he fells like I can show off my ring and our impending marriage because people ask about my ring, while he has to mention it on his own. He say's he's so proud to have me and he wants to show me off (aww!!) so has anyone ever heard of a guy wearing his band while he was only engaged. Our wedding is next march so he still has quite the wait (31 and a half weeks!!). Thanks all!!
