Answer:
Honestly man, the best way to do this may sound funny but it works. When you go pee, force yourself to stop mid stream and hold it for 30 seconds and then go again, keep doing this the whole time you pee. (Very important: you do not force yourself to stop by squeezing with your hand. It helps to act like someone just walked in on you.) This will help you build up a muscle called your kegel. After a little while you will be able to control this muscle better and use it at the right moment to shoot farther.
