Guys, guys, you're thinking about this the wrong way.
The proper strategy is to treat it as a warm-up. Assuming you have a girlfriend who will come back for more afterwards, this is what you do:
Start pumping and get your heart rate going.
Just when it's getting good and your girl wants you to finish...
Just leave her there dripping wet while you've got a nice adrenaline rush going on, and start heading for the game to suit up.
Granted there is the risk of pissing her off, but at the end of the night she'll be sexually frustrated enough to finish the job and potentially reward you for a good game
