Jeesh GuySmiley,
One of you two will be disappointed while the other will be elated. You should make a sexual bet with the SO of some sort where the winner has the loser perform a specific naughty act on the other.
(ie she allow you to go to the Greece or you eat her out for a full half hour)
Then you both will be winners in my book.
That or makeup sex will be funners.
