Thank you for posting this query. First of all, at your age, the possibility of you having prostrate cancer is less than 0.00001%. Just say it is old people's illness more than 40 years. If you are urinating and drinking frequently it is possible that you either have an infection or a metabolic/electrolyte disorder. So it will be useful to conduct a urine analysis and blood electrolytes. Since you said, your blood sugar level was tested and it was normal reason for conclusion you do not have diabetes
. I will suggest that a fasting blood sugar be run at two different instance of more than 6 hours difference.
If there are abnormalities in your urine analysis and electrolytes it can be treated accordingly by your doctor.
There is another possibility of your frequent urination
being due to the two much humidity or increased thirst or even two much dryness. When you feel too thirsty, you drink too much water and subsequently urinate frequently. You might be having an abnormal physiologic disturbance which if allowed with time and change in environment, you will gradually stop urinating too much.
In any case which you a quick recovery and hope you meet a doctor soon enough to run some test.
As for your masturbation
problems, i think you need a lot of counselling
from a sexual disorder
specialist. It will require a lot of discipline from your part to stop masturbating and you need to be treated from your chronic masturbation addiction.
Hope this helps
