It sounds like you may be experiencing temporary irritation or sensitivity in the area following masturbation, which can sometimes cause mild discomfort or a ticklish feeling. The increased urination might be your body's way of flushing out any excess stimulation. If the sensation persists or worsens, consider consulting a doctor for further evaluation.
