You can't convince him of anything anyway, so why try.
All you can do is tell him that you love ML to him and think he is a fantastic lover but if he doesn't feel that way, then he will have to work through it.
He knows this is the truth anyway.
There was a brief period in which I decided that H didn't want to ML to me because I was fat, ugly, you name it. He would try to reassure me this was not the case but I was a bottomless pit of neediness and wanted even MORE reassurance.
He eventually stuck with one saying: "I do desire you but I'm not going to argue with you about it. Either you believe me or you don't, but there it is." That ended the game for me.
Now I don't always FEEL desirable around him but I no longer let his opinion of me decide what I am all about.
In short, tell him you think he's a great lover but that you can't convince him of squat.
