Can someone help me please?!!?

I am really wanting a baby and we’ve been trying for a year now with no success. My boyfriend doesn’t get all the way hard and even though he has what he says is a orgasm absolutely nothing comes out when he finishes. He says this is something that has been going on for a few years now. He is diabetic and was off of his medicine for quite some time. I finally got him to get back on and he has been taking it for 2 weeks now. The problem is he refuses to talk to the dr about his sexual problems bc he finds it embarrassing and says it’ll be awkward. Is there anything at home I can do before pushing harder for him to go to the dr?
