I would say in order for anything to "start happening" in that area, maybe one of you needs to just "go for it." He may be thinking the same things you are and doesn't know how YOU will react if he tries something more.
If you are pretty sure about the fact that you two are working on reconciling, I would say go ahead & do what feels comfortable.
