Lucky bastard, your man.
What can I say. Having a woman who confessedly wants to do everything to make you happy, is all I could ever wish for. And obviously that isn't just words in your case, unless you're full of shit. But I'm going to assume not, because it doesn't really matter anyway.
But come on, this is your guy. You know him better than anyone of us. You should know what makes him extra happy, you should be well capable to find out.
You already got all the basic things covered. Sex, food, tenderness.
How you do these things will always be best your way. If he is anything like me, he will be most appriciative of your personal touch in these matters, because he loves you.
I don't think you need others ideas. Let this remain a thing between you and him. Just pay attention and pick from your own imagination for surprises. It will be worth more to both you and him if you came up with whatever, by yourself.
I consider this a serious answer, hope you will too.
