I want him to NEED me

my S/O and I have been dating for over a year now. every time we have sex I feel like I'm the one who wants it and is the one who inittiates it; and he just goes along with it, because why not. So I was wondering how do I get him to be absolutely crazy about me. like he can't wait to get my clothes off me kind off wanting and need. He's a very laid back guy so if there is no sex he's 100% ok with it if there is sex he is also 100% ok with it. But I want to drive him nuts about me. Any suggestions?
