I’m 59, with Type-2 diabetes, and believe I have erectile dysfunction as I rarely get erections. I wake with a soft semi-erection but do not become firm. My blood sugars in the morning are between 6-8 I’m on 4 x 500 metformin 1 x gliclizide 1x dapaglifozin 20 units of lantus insulin before bed. I don’t get sexually aroused with lack of feeling or limited blood flow to my genitals. What can I do pls?
