I know I'm not a male but I do have some insight if it helps:
I've been type 1 diabetic for 12 years and for 10 of them, I hid my diabetes from the world and it didn't work out for me very well. I checked my sugars when it was convenient for my work, which was never and I can't tell you how I made it through. It must be that I'm still young...although, diabetes doesn't care much for age as much as length.
You can work any job you chose, but diabetes has to be number 1. I work retail and a daycare. They know what my priorities are and although it may annoy them, they can't deny me my rights to live healthy and happy with my "condition."
What's more, don't let diabetes inhibit you from daily activities, like work. When this disease becomes a chore, most people become irritable and denial-ridden.
Brokepole said it best: The sky really is pretty much the limit. Find a balance in your glucose and work whatever job you please.
