How awful this must be for you. My DH went through a similar
problem, in the early days. It was a form of denial. My Mom,
although supportive, believed that I was faking some of it.
So my support system was looking a bit grim as well.

DH, at that time, didn't think I could feel anything while making
love. Men can't help but think with their lower brain, at times.
After proving him wrong, he became so much more supportive.
Because, he then knew he was still in control, so to speak.

This was just my story and is, in no way, a solution to your's and
DH's problem.

Here's hoping that you and DH may, if not talk it out, work it out.
Take care of each other..
