Slightly overwhelmed

Hi there,
Brief bit of history.
I (33F) am newly married to a man of similar age. We were both virgins. We were pretty open about everything, to the extent where I'd told him it was probable I'd have difficulty with penetration due to previous medical history. I just couldn't be sure.
Well.. it turned out that he just can't O with me. He'd denied both PMO and MO when I'd asked him about it before. It was only when things got going that we discovered he can have and maintain an erection but just not come. That's when I learned about "death grip" and he admitted that was the issue. He'd been MO but didn't want to admit it. I do suspect that it's PMO too but as he denies it, I don't feel it would be wise to ask again. I do feel betrayed because I was so open with him. Sometimes he loses the erection which is frustrating. I know it's not his fault but I also feel it sort of... Is?

I'm not really sure what to do or where to go from here. I want to help him overcome this but it's difficult. I keep thinking that he can't possibly find me all that attractive but he reassures me that's not the case. Especially if he's been watching porn, I simply can't compare to the perfect bodies on screen.

He's happy to abstain (he says) from MO until he gets some sensitivity back. Does anyone know how long this can take? What's the best way of supporting him? I may sound unsupportive but I'm just trying to process this in my head. I want to help him with this.

I also feel guilty because penetration isn't a possibility at the moment. He's the kindest, most gentle man and he's been very good with me and we've definitely had fun in other ways.. he always makes sure I'm satisfied. I know many men wouldn't care. I just feel so lost and was hoping someone could offer advice.

Thank you for reading.
