The need to urinate occurring during masturbation. Continuing to ejaculation often results in a less pleasurable orgasm. This often happens upon waking up with morning wood.
John woke up with a hard-on but he also needed a piss. He struggled on and after his ejaculation wondered why he had bothered with his pisswank after all.
