Personally, Tony had no more coordination. It's a good thing the world's not in danger at this very moment. Because him trying to fly around in the iron Man suit while he's this wasted? Not a good thing. Talk about misfiring.
As for ending up underneath the buxom babe of supernatural superheroics, Tony just finds the bed as comfortable as ever. So soft. Mmmm. Almost as soft as the woman straddling him. "Guilty as charged. Wanna' help me out here?"
