Besides screwing up your heart, eyes and kidneys and inviting host of other medical issues, the biggest kick in the butt is ED. You just can't get it up, even if you have nude Katrina Kaif in front of you. You must get your FBS and PPBS under control, under any circumstances. Must make Lifestyle Changes, control Diet and Exercise. If oral medication is not sufficient, get Insulin under medical supervision. There is no shame ! Get your diabetes under control and you will see marked improvement in your sexual health. My personal experience.
