It's not a nice situation to be in. You don't fancy sex, he sulks, you feel you can't say anything because he does do practical stuff.
You're menopausal, which brings it's own problems, but at the same time he is younger than you, so you don't want to keep pointing that out.
It sounds like there are a few things bubbling under the surface which are making you feel insecure.
Which then makes it quite difficult to talk, because that can make you feel even more vulnerable.
But this will just keep milling around under the surface unless you do talk. But wait until you are both in the right frame of mind.
You need to feel confident and he needs to not be on the defensive.
If you can pick a time like that, you stand a better chance of both being open, without it degenerating into a row.
If you can go in with the idea of a resolution, being supportive, etc, the conversation stands a better chance of success.
Although it always pisses me off that it's the women who ruminate on this, not the men.
