This has happened to me a couple of times. Once, I went on a date with this girl - we talked for over three hours, and by the end I was kissing her neck and fingering her while her hand was wrapped around my dick. No response to my text for a second date.

Then on another occasion, I had yet another date where we did not run out of things to talk about for the 90 minutes we spent together. That ended with us making out by her car. She did not respond to my text about hanging out again.

What gives?
