Question: I have a problem with not lasting long enough when having sex. (Maybe 5 minutes) Is this considered premature and would it be due to diabetes? What can I do?

Technically a 5 minute orgasm does not constitute premature by definition. However if your parter expects more, then it could be premature according to your relationship. As for the diabetes being involved, there is evidence that points to sexual dysfunction and premature ejaculation being worsened by diabetes. Essentially all you can do at this point is work on maintaining your diabetes. There isn't a lot more information on this subject at this time.
