From personal experience, I would imagine all men have the capacity for both short and long distances.
For me at least, faster stimulation that is maintained during orgasm results in a faster shot. With slower stimulation or stimulation that is interrupted during orgasm resulting in a slow one.
Also, if the erection has no resistance put on it, pointing upwards, then it will tend to be a slower one, but if the erection has resistance put on it and is made to aim downwards it will result in a faster one.
at least for me
