Both lovely ladies are right; there is very little chance that the sperm had found it's way inside. Once it hits the air, most of it dies off after a short time, and dead sperm can't fertilize an egg. I wouldn't worry too much about it, and you should make sure she isn't worrying about it either. Stress can cause her period to be late, or not to come at all so it's best for both of you to stay calm. In two weeks, have her take a pregnancy test to ease your minds.
