DH and I have been through this in two different ways. ED (Impotence) and lack of sex drive (Hormone problems)

I think its important to understand this his inability to "function" is probably medical. Like 90% or more. If its medical its very common so he should not wig out. However its never "normal" no matter what his age. He needs to find out why he is having this problem. Men with sexual health issues are loth to see doctors... Why? Many reasons... You can help. Assure him that its not a "failure to be man" its a medical problem. Tell him that your feelings for him are not changing because he has a medical problem. Help him find a doctor he can talk to. Some men don't want to admit their problems and finding a doctor he trusts is very important. If you feel angry and resentment remember this is his medical problem. He might not be dealing with it well but its not "rejection" of you in a sexual way. Its not because your not sexy enough or are too fat or anything like that.
