I masturbate daily. From two months I have sharp pain in urine. I stopped masturbation for some days. I had no pain when I did it again. After some time I found some red tissue like thing in urine and I was fainted. After some gap, when I masturbated my urine colour changed to pink. I have pain in the urinary track sometimes and sometimes in the starting of urinary track and sometimes I felt like blocking of urine due to red tissue. I also feel some burning sensation in the track. Is there any serious problem?
