Pain and Itch resolve by masturbating

I feel some pain in my pussy lips and itchyness with my pussy and I'm so lazy to scratch it using my hands. It's a natural pain and itch not a libido itch so I decided to use my massager and massage my push until I feel arouse so even pain and itch is over I continued it but unfortunately i urinate and its shit. I hate it. But I love the massager and the feeling. I wish I got arouse and climax with no urinating shit.

How can i do that with w/o urinating?
