Guys are so silly like that. When I got engaged, I could not wait to ask my sister and friends to be my MOH and bridesmaids. Guys just seem to feel awkward asking for some reason or other. My fiance was the same way. He didn't want to ask his guys right away and did it on his own time when the situation felt right I guess. When my sister got married, the same thing with her husband. He didn't ask any of his groomsmen until one night when everyone who they had planned to be in their wedding party were hanging out, he was like, well the whole wedding party is here. And the guys were like, um, okay so I guess we're groomsmen. Must just be a guy thing that us girls don't get!
