I was diagnosed a type 2 diabetic four years ago, but since then I lost 60lbs. I'm now told that I'm back to pre-diabetic, but am staying on Canagliflozin as it is also supposed to have benefits for those with mild heart failure. I am 75. The diabetes has worsened my ED and I've lost the ability to get an erection even with maximum doze of Viagra or Cialis. Penis pumps provide a very temporary erection, but it almost instantly dies (in seconds). My question is - now I am only borderline diabetic, will the sensitivity return to my glans or is it lost forever? Thank you.
