Since I've been training, I've been noticing fire currents running through my hands and feet. Maybe pyrokinetic, if you are finding it easier to roll the pen after lighting it, you may be pyrokinetic as well, and the fire energy with the pen after the lighter helps you match up with it, making it easier. See if you can do other things with the pen after lighting it, rolling from side to side, pulling, spinning, etc.
Just my theory, but I think it makes sense. Never know until you try, right?
