My simple advice is to continue "not believing" what he says. He is still confused. He is enjoying your new R and maybe feels like introducing sex into it would spoil it somehow. That's just speculation and like I said, what does it matter. What he says right now is pretty irrelevant. What he is DOING is hanging around more, feeling the situation out (no pun intended...well, sorta) and probably not trying to think much about it.
I would not pursue this much right now. I know in my sitch, I just think it's too soon. You let it be know you were open to it and he declined...for now.
I would not say that his reluctance to it now means you are destined to a sexless marriage. It is just, to me, more evidence that you are destined for more work before you really DO get to a point where you can discuss and then HAVE sex.
In the long run, at some point, I think you WILL (just like I will) have to talk to him openly about what you want and need in terms of intimacy and maybe YOU will be the one at that point, should he not ever get on the same page, to walk away from the marriage. I don't think you are there yet, and may not be for some time.
Patience. After all this time, what's another few weeks...months...
Keep building on the foundation, make it strong so that when you have to start putting on the walls and eventually talk about what kind of roof (sex) you want, it will hold up under the stress.
