Though I'm far from super-knowledgeable, lol... I'll throw in my .02.
Most likely you've just been lucky. If the guy could always reliably do it, pulling out would probably work fairly well. It's just that its not the natural (or easy) thing to do, and most people don't want to take the chance. With all the factors involved in getting pregnant, I'd say its not unreasonable to just say that you were in the small number of people for whom pulling out has worked
Now, I'll step aside for the experts...
