All I will say is this. DO NOT COME TO MY WEDDING.
Y'all will be waiting on me to take pictures and I will be "busy" in the same room where she got dressed, the room where I got dressed, and maybe the kitchen if the coast is clear.
One thing the photographer will NOT have to say to EITHER of us is....smile.
All I got to say, is good luck finding a woman who will oblige. I can't imagine many self-respecting women who want to get busy in a church, let alone in a place where their great gramama and aunties are around. I can't imagine a bride who will risk getting their hair and nails messed up that they paid a king's ransom for, right before they take pictures they want to preserve for posterity. I also can't imagine a bride who isn't stressed about wedding details, guests, family members or crazy uncle Jerome who brings his own bottle of Crazy Horse for the reception who auntie Shirley still holds a grudge against. Add those things up, and it'll be hard to get into the mood.
There's a reason why you have a honeymoon, you're away from the stress of the wedding and family members to enjoy each other. She's your bride. Just because you are married, doesn't mean you can bend her over like a $2 ho in a bathroom (on her wedding day no less). If she's holding out too, I'm sure she's expecting something a little romantic for her wedding day.
That's why you have a reception. To keep everyone else occupied and entertained until you can make your getaway. Get a good band/DJ and good food, and you can make your escape early.
