I'm peeing a lot, drinking "normal"amount of water, it doesn't hurt and no fever. any idea of what could it be?

Frequent urination: Can be from a bladder infection but also from some other causes. It may result from an infection of the urethra and might not have the same symptoms as a bladder infection. Perhaps most importantly, you should see your healthcare provider and talk about the possibility of this being a symptom of diabetes.

Check the urine: Excessive urine is sometimes a sign of diabetes but there are many other possibilities. If you have no other symptoms at all, it may not be serious but you should be seen by a doctor. A good history and physical exam plus a urinalysis may be able to answer the question.
