Guys, let me just say that you have nothing to be worried about. Time and time again I've seen one of two things happen,

1. Your bros will help you out on your wedding day, be it tying a tie or remembering that "thing that goes on your finger" during that really "important time" at that "thing" you are going to be at by 3pm.

2. Mum will still iron your shirts and pants. (Even if you're 32)
