Dear DH, I'm a 47-year-old man who was diagnosed with type 2 diabetes in 2008. For two years, I haven't been interested in sex. I have a demanding retail job and two teenage children. I can still perform, but I am usually so tired that I fall asleep after dinner. I don't miss sex much, but my wife does, and I don't want to lose her. By the way, my A1C usually runs around 6.8%.
