I met this girl on St.Paddy's Day. We hit it off great at first, lots of touching, sexual innuendo, friends gave me tons of social proof, etc. I end up pulling her to me place and fucking her during the day. We're at my place for a few hours, maintaining a heavy sexual vibe the whole time. Next we go to pick up her car and hang out with some friends again. Then we get some food and head back to my place and fuck again. She leaves early in the morning. Throughout the day, we trade snapchats and texts.

We texted and snapchatted off and on throughout the week, but I got blown off this weekend. I want to fuck this girl again and make it an FWB/casual dating type thing. How do I regain the edge?

Some background info: I'm 26, she's 24. She's works full time and goes to grad school, so she is actually busy pretty often and doesn't really go out much (heard this from mutual friends).
