my diabetic fiance and I are intimate with eachother, and I mentioned in my introduction he has had diabetes pretty much his whole life. Occasionally there is difficulty and of course ensuing stress with difficulty of achieving intimacy. sometimes things go smoothly, other times... not so much. He monitors his sugar levels before, always makes sure he isn't borderline low before anything. He mentioned sometimes he cant feel much there. How do I approach him with the possibility of ED? He isn't even thirty yet, that seems like (pardon pun) a low blow. I dont see how it couldnt have possibly crossed his mind, most likely he is being stubborn and doesn't want to admit it. I have tried doing some research on ED, I haven't gotten very far, and there isn't much on how to figure out if it is actually ED or something else. If there is a problem, it needs to be fixed, I very much want to have children with him someday. Anyone have any further resources or advice for me? Thanks!
