Newly wed

I posted this on Relationships but I think this is the best place for it. I just married my best friend and couldn't be happier about it. Hes very caring and I know he loves me... but we have a sexless life. I'm not happy about it, but I dont know what to do.

I've tried coming on to him, but am constantly rejected. I wait for him to make a move and it never comes. I've tried talking to him but he always says theres nothing wrong and that hes just physically tired.

When we started dating 4 years ago we were into trying me and doing some pretty unorthodox things, I want that back but dont know how to get it back. I just dont know what to do anymore...
