As Graniterose said I assume he went to the Dr. - but did the Dr. do a blood test and check his testosterone level? Inability to maintain an erection is a symptom of low testosterone. I finally went to the Dr. (after my wife filed for Divorce citing, amond other reasons, my lack of a sex drive) and found that not only was my Testosterone level low - it was very low. I am now taking a Testosterone supplement and it is having an effect not that it does any good now. Even tho WAW and I still talk and seem to be making some progress in restoring our R, our sex life is nill because of her hurt. Funny thing that when I could, I didn't want to but now that I can't, I really want to.
Dr. also gave me the wonder blue pills since Viagra may need a Testosterone boost to really work. Just my opinion. ODGA
