So I recently met up with a girl I met online at a bar. I took her home and we hooked up, meaning lots of making out and touching. There was no sex, but I enjoyed it a lot. This girl isn't really my "type," so (1) I'm not interested in anything serious with her and (2) I figured I should let her chase me (as so many PUAs emphasize). Well, I was going to make plans with another girl this weekend, but they fell through, so I figured I'd text this first girl and arrange something. We haven't communicated since we hooked up and it's been five days. She replied pretty quickly saying she was surprised to hear from me but she was free.

It feels really awkward that she would draw attention to the fact that she didn't expect to hear back from me. Now I am concerned that I made a subtle mistake ... and if I'm not careful, I will make more subtle mistakes by creating a false impression that I want something serious.

Okay, questions. I want to sleep with this girl and have her as an occasional FWB. (A) What "date" or activity can I plan to make my intentions clearer? (B) How do I more generally steer this in the right direction?
