Couple questions...

have you given birth to any children?If so, was it recent?

Did you have chronic UTI as a child or at any time in your past?

You say you have no muscles - you do have the muscles, but it sounds like poor muscle control may be a factor here. Are you sure you are doing the kegels right? Alot of people dont(including me before i knew what I was doing)

The easiest way to do a kegel for the first time is when you are urinating, "stop" the flow or slow it down. You may not be able to fully stop it if your muscle control is poor. Thats the action you should be taking when doing a kegel.

I would see a urologist if you can, and have your muscle tone evaluated and also have them do an ultrasound to check for bladder inconsistency. Just to be sure. KUP!
