My now husband and I have never truly had the passionate kisses you speak of. Except for one night when he got drunk at his cousins wedding, and kissed me, passionately. It was in front of his whole family. It was the first time I met most of them, but not since.
Now....I can't get my lips to work right. Even if I could, I would feel so odd about anything like that due to the half a tongue, lol.
I don't know if your husband feels the way I do about it. I know this has definitely made me insecure about kissing or anything else I used to enjoy doing to make my husband happy. I am kind of glad the lips don't work right, but sad that I can't kiss my husband and make him happy in those ways anymore.
I have found other ways to try to still get the same end result. Just doing different things, and it's not the same, but it's the thought that counts.
I can't say I know exactly what is going on with your husband. If he's insecure about it, or is worried that it won't work right anymore, then I am not sure what will fix it. It may be possible that he worries about what you were saying. If he says that's not the reason, then maybe try your best to get that out of your head, because he is your husband, and why would he lie to you about that?
Hope you guys get things figured out and can compromise somehow, or find something that he is willing to do that will make you happy.
Instead of passionate kisses, we have passionate Cheeky's, lol. hahaha. Maybe get a little creative with your hands and some lube. So if you are both willing to compromise instead of "punishing" maybe both will be happy,
I am not saying you can't be upset/hurt by this. I know my husband was upset when I wouldn't kiss him anymore, at least at first. Now that he has seen time and time again when I would try to kiss him, and my lips just wouldn't cooperate. Then he saw how sad I would get because of it, he is willing to settle for cheek cuddle.

In the end, I hope you and your husband can find something that makes you both happy. Get things figured out so you don't feel so deprived of those good things you had before.
