My partner of 20 years has issues and always has. They come and go. Really-I just don't care about the issues (not that I don't care about him).
If he can't get it up, we do other stuff. It's never been a problem. When it gets up-we have intercourse, when it doesn't we don't.
From an emotional standpoint I think this has been helpful for him-because he knows (after all of this time) that whether or not it gets up is really quite irrelevant to me. Sometimes frustrating for him-but irrelevant to me. It has no effect on my sexual satisfaction.
