Too much sugar in the diet can wear out your pancreas and cause type 2 diabetes. Diabetes causes the most difficult to treat kind of impotence. Nobody ever tells guys that ahead of time.
Hi NickYou have put your finger on it but cant see it, I'm talking about sugar, if you also take lots of sugar in your coffee and tea, thats were its all coming from and lifting your libido up and over the top, get the sugar cut back, and the you will fill better and and cutback on your masturbating, when you can bring your masturbating down to a couple of times a week, the will make things better for you as well.
Good Luck
