How soon after seeing a women does a man know he wants to be with her?

How soon after seeing a women does a man know he wants to be with her? And how can I ask him what he wants without being too pushy? Especially if they both did not have any clear expectations at the start of their courtship? For example it took me 5 weeks to realise I actually like him. I wasn’t sure how I felt at the start.
