I am a 58 yr old man 5’10 @ 190#. I have been on two types of insulin for over 12 yrs(taken daily) Diabetic #1. I have also been taking high blood pressure medicine-10 mg daily. I cannot get an erection PERIOD. It has been over four years since I remember what it felt like. I cannot have relations with my wife. I cannot masturbate, other than yank on a noodle…eventually just giving up. My endocrinologist has tested my testosterone (said it was in the normal guidelines) but still issued a testosterone ointment to see if this could help. He has also over the years prescribed Viagra and Cialis. (Again nothing works). I have desire when I see a woman (or my wife) but that is now a moot issue because I cannot back up that desire, no matter how long or how wildly she tries to stimulate me. Four years of hell sexually, really weighs heavy on a man’s mind. Do I throw in the towel?
