Not at all!!! My FH is having 2 best men and I’m totally cool with it! It’s too hard choosing. He’s been best friends with these two guys since one elementary school ( btw what is it with guys keeping friendships that long!? Or is it just me that’s jealous of that?)
I have two - one Man of Honour and one Maid of Honour. I couldn't possibly pick between the two. One is more involved than the other, but they are both so important to me, and they're both really cool with it.
All told, there are seven on my side and seven on my fiance's side.
Are either of them married? I was debating between 2 of my girls and realized I could have a Matron of Honour and Maid of Honour...
Either way, it's your wedding, you can do whatever you want... maybe talk to them though. I know I really felt honoured to be a part of someone's wedding, and although I'm pretty easy going, I don't know how I'd feel to share that. They might both be cool with it, or one or both might rather you just pick one.
I currently have two co-mohs, one didn't think it was traditional and the other was fine with it. bit of drama but honestly if it was me and someone else as co-moh in a wedding party I would be fine with it.
