Did he switch to erotica after the A? If he did, he most likely will not tell you and might be good at hiding it.
Ed will some/most guys for a loop so some or most of what he tells you could be true. From what I read some guys will say they lost interest in sex but many times the talk is not reality.
The ED is not strictly age related so don't count it as normal just because he reached a certain age.
Sometimes when I can't sleep, I take care of myself. Once in a while I wake up in two hours and do it again. I even have morning wood and if my W was willing, I would go again. Usually once is enough. (FYI I am 63 and this is for informational purposes only)
I googled "when sex is over" and found other guys in M's where the W didn't like sex or wouldn't engage in sex. Some of the guys were in their late 60 / early 70's.
Having ED is a curse for most men and does strange things to the guys thinking. Having a W that doesn't like sex is no fun either.
(this is embarrassing) Gwyn, first let me invite you to not be embarrassed. Once you post here, what you have posted will seem tame.
The SSM forum is a place where questions asked, thoughts shared, becomes a growing process for everyone.
We are all just cyber friends in similar leaky boats, bailing the water out as best as we know how and need/give support to all of our sometimes “best friends you never met.”
