... but that's partly just me and my melancholy nature, and my own recent troubles ...
I can't add too much to what others have said. But as you asked for old guys' opinion, and I definitely qualify, I'll say to this question:
"Why would a guy so much older be intimidated???"
There can be all kinds of reasons. If he's having erection problems, your willingness to be patient is great, but sometimes we guys can't accept that or are afraid to believe it, or are too wrapped up in our own anxiety and misery about the issue to take in that our partner cares for us and enjoys us nonetheless.
Or his being so much older could be part of it. Like, "Surely she can't really be interested in me, I'm so old." "A younger, better-looking guy will catch her eye, and that will be that." "I'm not in bad shape now, but will she still like hanging out with me if I start falling apart?"
Things like that.
[Edited to add:] And any of these issues could be magnified, in his mind, by your being a provider and having--again, in his mind--such a wide range of experience with so many other men to compare him to. I can well imagine that it wasn't like that for you at all, but the fears and doubts that come to a guy, young or old, when he's feeling uncertain and vulnerable are not easily overcome by reason or reassurance.
We get old, hopefully we get a little stronger, a little wiser, a little more comfortable in our own skin. But we don't stop being the person we were when we were younger, and that sometimes means some of the same insecurities of youth or even childhood hang on to bedevil us.
I wish, for your sake and his, that he could have gotten over whatever it was. (And yeah, more selfishly I hope for my own sake that if I'm ever lucky enough again to be in his situation, I'll be able to keep my bearings and hold on to a good thing.) But that was his issue, not yours, whatever it was. It sounds to me as if you did all you could.
