I'm more a go-with-the-flow kind of woman. It also means that the guy will have to take the initiative. Given I agreed to go on a date, everything's fair game from that point on. If the guy makes a move, I won't back down. That being said, I haven't slept with anyone on the first date or second or even third. I'm good at boner killing conversation, I think. :3
Now if it's a casual hookup, that's another matter altogether.
