I read somewhere that wedding night sex is not the norm. My best friend said she was just too tired to bother, and besids, she'd had sex with him for years beforehand.
There is a lot of this. My friend N. decided to have an afterparty in their hotel suite instead of sex since it was probably going to be the last time we were all in the same place at the same time. (Which turned out to be very accurate.) We had a lot of fun. Especially when she kept making her new husband carry her over the threshhold again and again.
I was at a wedding once where the bride did the bouquet toss. A space wide enough to drive a humvee through opened along its trajectory.
HA! At the same wedding, we had a similar incident. There were four of us who were single. When the bouquet came towards us, we all took a step back. It landed on the ground. N retossed it. Same thing. Finally, one of my fellow bridesmaids picked it up to hand back to the bride and we were all like, "Nope! You touched it. You're it."
