Hack #11: Dealing with DILDO: Diabetes-Induced Libido DisOrder

I'm hoping I just coined a new acronym for something that very few people seem to be talking about: DILDO. No, not the vibrator thing, but it's kind of related. I'm guessing I've invented a new term because very few people seem to be talking about - or admitting - that diabetes can have an effect on a man's libido, or sexual function (I can't comment about possible female-related issues). Yes, there will be passing references about it. But possibly because there's shame and fear related to the topic, or a lack of specific therapies to deal with it, I've been unable to learn much about this problem, and so I'm cracking open the topic, and giving it a MEMORABLE NAME ("Excuse me, do you have DILDO?" "Are you experiencing DILDO symptoms?"), and talking about my experience with it in the hope that others can feel better about it or have some hope. 
       Last summer apparently, my pancreas finally gave up after 50+ years of doing its job, and I began to lose weight rapidly, and experience extreme thirst, cramps, loss of appetite, only to learn that my blood sugar levels had jumped to 300+ and my a1C was near 20% (a normal a1C should be below 5%). BUT, in looking back, I know that for a few years now I'd been "borderline diabetic" with an a1C hovering just over 6, and I was just supposed to watch my weight and exercise and wait to see if things got better or worse. 
       Well, on a separate track, for the past few years, I also was feeling like my interest in sex had declined significantly, from several times a day to only several times a month. For better or worse, however, I wasn't experiencing sexual disfunction, or the inability to have sex. I just wasn't as interested in pursuing sex (or even fantasizing about it) as much as I had been for most of my adult life. This led me to have expensive bloodwork done to determine whether my testosterone levels were below normal, which they weren't. I also tried taking DHEA to see if that helped (which it didn't appear to). 
       So my question is: are middle-to-later-aged men treating their lower libido with pills like Cialis and Viagra, just like Type 2 diabetics are treating their insulin resistance with insulin, when in fact these problems are better treated in other ways (in the case of T2D, diet an exercise are better "fixes" for T2D vs. loads of insulin)? Now, the trick is, I don't know what the "fix" is for a lower libido, but I wonder if it has to do with my new T1D condition, which came along around the same time as my lower libido conditions. Anyone have a similar situation, and any ideas for improving things?
