I think your 'plumbing' is set up to produce pressure when cumming or not. Plus your ureatra size may have something to do with it. I'm guessing a smaller one would cause it to shoot out faster, all things being the same?

As a teen a few friends used to fool around in the neighborhood, and I'd show them how far I could cum. About 6 feet then. My one friend could shoot 2 feet or so, and my other friend with the biggest fattest dick just poured out.

years later I still cum far, but only a few feet now. just like all else, body there doesn't perform as good as a ****.

Actually I have always thought that when it goes in someone's mouth, pussy, and/or ass, that 'shooting distance' really doesn't matter much??

The 'Kegel' type of exercise will increase force of ejaculation coniderably and is used by porn stars.
