And if I submit an offer and they reply it makes them sick and they no longer want to talk, I've prematurely screwed myself for no reason.
I don't like making the first offer unless I have to. If my asking if they have demands is a problem, tell me how to amend my asking so it better suits your needs. I will not be making the first offer though. If that means they say that and then I just don't engage them any further, so it goes.
