I say, add "getting laid" to your wedding day to-do list, right alongside all the other tasks you'll go bat shit crazy over. And, if you're gonna make it a priority, you might as well get it right, no?
There will be plenty of opportunities in the coming years for a passionate night of love-making. If passing out after your wedding feels better than making out, so be it. You have the rest of your lives to make up for it.
