See Gyn: This type of activity should not prevent you from you holding your urine. SEe the gyn or urologist for the best advice. This may need some attention. If not serious , they will tell you.

Kegel exercises: are the best way to strengthen the muscles necessary to help prevent incontinence. see the website: http://www.kegelexercisesforwomen.com/ You did not cause this from masturbating. It would be good to see your gynecologist to rule out other causes for incontinence though. If you have given birth, or have a bladder infection, or have diabetes you can develop frequent urination and incontinence.
