Let me guess, you watch Peter North and want to do the same as him. Well, he does have a secret formula that he is supposed to release (no pun intended) when he retires from porn.
For me, when you are about to explode, resist letting loose until you can't anymore, then when you can't hold back, let it go. If I just ejaculate and not hold back, it doesn't go too far. If I hold back, I can shoot pretty far.
As far as volume, I am not sure how to increase volume, sorry.
I do know one thing for both distance and volume, if you ejaculate 10 times a day, you won't have much volume or distance. If you wait a week or so, then do it, then you will increase your chances of getting the results you want.
