Uh, why would you think you have to urinate every time you reach orgasm? When you get old, you'll feel a need to urinate after you bend over, but you're probably quite young and so if you don't have to pee you don't have to pee so don't pee until you do have to pee. As long as when you do urinate it works fine and there's no long time period before something comes out and nothing hurts and you aren't peeing on your foot, you're good.
