He wants kids and I don't but put in a compromise that lets have kids after 3-4 year of marriage but he didn't like that?

I'm 30 and he is 41 and he is conscious of his age that his chance of having kids might run out and said I should be conscious of it too cause I'm 30 but didn't say I was old or anything.. What should I do?
