If i have sex on the 7th will that sperm fertilize the egg before sperm during sex on the 11th?

Hmmm....: Have never known sperm to be selflessly polite, and swim in place (they can't stand in line), waiting for sperm from an earlier day to go first. However, many sperm from an earlier day would likely have tired out by the time the newer sperm arrived on the scene. But still, nobody knows. If one man, it doesn't matter. If two men, the rule is to separate men by at least TWO weeks. It's a good rule.
