The guy is actively trying to get the help of other women. That's more than 99% of most men will ever do.
Give him a fucking break.
When you begin a relationship with someone, you expect sex to be a regular feature. That's not rocket science.
If sex is not a regular feature, then it isn't the same relationship any more.
If it's not the same relationship as it was before, everyone (man or woman) has a right to work out how to fix it, or to end the relationship amicably.
To everyone saying "I wouldn't give handjobs or oral" then I can only imagine you don't give a shit about your partner, or making them feel good. If I wasn't able or willing to have PIV with my OH because of a problem I had with my body then I'd damn well make sure she felt comfortable masturbating while I held her, or I would use a vibrator on her, or my hands or oral or whatever else she fancied - because I care about her wants and her needs and I want to provide for them as best as I can. If I said "Sorry hun, I'm not touching you ever again" then I wouldn't be at all surprised if she said "Okay, bye then" because otherwise you're basically living with a friend, and not a lover. That's not what she wants or needs, and I'd let her go if she wanted to.
The menopause sucks, yes it does. However in this case it's a decade early and not anything he could have anticipated or expected. Not only is sex off the cards, but so is even a kiss or cuddling. How long is he expected to maintain that? If I was faced with the rest of my life with no physical affection at all, then I'd be right out of there too because I'd be fundamentally unhappy the entire time. She deserves someone who is genuinely happy with no intimacy, and he deserves to find someone who wants to touch him. It's nobody's fault, it's just a case of "Shit happens" and there's no reason for both people to be miserable if there are other options for both of them.
I'd keep going with whatever remedies and solutions you haven't tried yet, avoid harassing her, reassure her that kissing or hugging won't lead to anything more, and masturbate as much as you need to. Eventually either it'll get better or you'll get so frustrated that you'll end it. Only you can know how long that'll be.
