I think you either accept that you've had plenty of fantastic sex in the past and you can live on your memories, and hope things improve in the bedroom, or you try talking to him to introduce different locations around the house and get a bit excited after a few drinks, see what he's like, or just accept you're not going to fundamentally change someone's ways at this time of life, and you are grateful for his other presumably loving and kind qualities.
I never fake it, I make it clear, in a nice way, that it didn't happen for me this time, it was a nice feeling, but hopefully it will happen, i will orgasm, next time if we try this or this.
Basically you sort yourself out in front of him, if you have to. Because all the happy hormones will come then, and you'll feel better about it all. And give it half a chance.
And if you can't do that,but you can use toys, which i don't currently like, then there's an issue imo.
You cannot pander to other people's feelings to that extent.
Its a slippery slope.
Quite literally 😅
