2-3 months back I started to get more premature ejaculations , one day while masturbating I felt a sudden pain on both sides of my lower stomach(i assume that that's where the kidneys are) .....
Since than whenever I masturbate and my penis is erect I feel like urinating(i get like a heavy bladder) however before my penis is erect I don't feel the need to piss.
If however I manage to urinate completely before masturbating the kidney pain returns.
Sometime the urine seems acidic. Please help if you can!
