ED: Intermittent erectile dysfunction at your age is not likely due to DM ( unless you have had DM for many years ) especially if you are having full erections then losing them. Seems like you may have some psychologic component. Your DM does need better control. This will prevent ED in the future. In the interim see your doc for a full eval and to consider therapy for your current problem.
