No.

He may, or may not, have a number of different motives, possibly simultaneously: he likes you, he finds you attractive, he wants to have an affair with you, he wants to jump on your bones. We don't know him. You do.
You haven't said anything about your "motives". If your intention is just to keep it light, have a drink, be friends as two adults, etc, then you would make sure that is all that happens. If you want (or are ready for) more than that, then that is possible too. Welcome to the adult world.
