It depends on a lot of things: the atmosphere, my own mood, chemistry, the girl's mood, lots of things.
I try and get a sense of a girl's personality, and try not to let looks be the ONLY determining factor. I've gotten burned doing that, including a party I posted about with a girl currently at the MLBR.
There was one time (not at band camp, how about "at courtesan camp"?) when I was at the Sagebrush, not planning to party, when a particular lady seemed to see something in me that told her I was willing to spend money on her. She would come up to me, tease me a bit, make an attempt to get me to party, and then back off and circulate a bit. She circled the room a few times, each time making a pass at me. She finally got me to go to her room and talk.
We started talking about how she could read guys pretty well, and she could tell I wanted to party with her. I was skeptical, to say the least, and asked her how she knew this, when inwardly I was still not planning on partying with her.
"OK, let me see if I can tell what kind of party you want."
"You can do that? Yeah, right."
And then she rattled off not one or two things, but about 9 or 10 things that I liked to do or characteristics of parties I like.
At that point I just laid the money in her hand.
