[Roger Gould, M.D.]

there should be no relationship between masturbation and urinary frequency.   you could find out for sure by simply stop masturbating for a while and see what happens.

I'm not well versed in male issues but you could have an infection.  ??

Ain't no muscles there, old boy.  But you could be rubbing it raw.  Be gentle, man.
