This is both a physical, mental, emotional, and psychological problem, and both of you will be involved in the solution.
But the first step is for him to get a complete physical exam, focusing first on the restoration of the blood flow in his pelvic region.
When the veins are blocked, or if he has a specific malformation, having difficulties can be the natural result.
The good news is that both problems can be corrected!
Additionally his hormone levels need to be checked.
If they are low, with medication, they can be brought back to normal.
And lastly, his psychological problems need to be delt with.
It is indeed possible that he has either knowingly or unknowingly accepted ideas into his head and his life that have adversely contributed to this problem.
His previous family medical and emotional history could also be a large part of his problems. So both you and the doctor will need to explore that with him, to see what his family's attitude towards married sex was about, and especially his earliest memories when he was a child of his father's sexuality.
A very good point for sure. But it’s not a possibility with us. He had a vasectomy over ten years ago — most of our children are adopted.
And another tie in could be his unexpected psychological reaction to that vasectomy.
Sometimes men don't know about how the unexpected loss of those hormones can affect them.
So if your husband didn't have a medical briefing on what to expect, post surgery, or was not offered a prescription to restore the loss of hormones, the shock of their sudden loss could be what's behind his withdrawal.
Think of it as a man's version of a woman's " Change of Life", where the hormones are suddenly shut down.
That could be the medical reason for many of his changes that you are seeing.
So get him to a doctor and get his hormone levels checked.
