Imagine you are dating .... when do you take it to the next level?

I am seeing some pretty scary stuff here, actually ...
... not as in chronological age ... I am interested in at what point in the relationship?

And does he have to buy you dinner? Or do you like, make him dinner? Or can you split the tab 50/50 and still get it on? I mean, like really. What's the deal here?

If a man spots dinner for another man, does the one who received the gift, have to continue to receive, once the meal is over?

Really ... I am at the edge of my chair, anticipating intelligent and well-thought out replies.
