I know that only a doctor can prescribe the correct treatment for erectile dysfunction. This is a rather delicate problem, but there is nothing worth it to be ashamed of. Your doctor will not blame you, he will just try to solve your problem. I know that most often a doctor prescribes Viagra or Levitra. (the difference between these pills can be found here Canadian Pharmacy
). Most likely you will not be able to find a dosage that is safe for you, so it will be better if the doctor tells you how and when to take these pills.
