Plate comes over today, to "get help with Calculus." I oblige, knowing there is sex to come. She plops herself on my lap as I explain how/what to do for her specific question.

Fast forward about 30 minutes, we're on my bed making out, she puts her hand on my dick, gives it some action, and then gives me a big kiss and says she has to go. I ask her where she's going, and she responds to get lunch with her roommate.

I sit in awe as she gathers her stuff, and then comes up to me wanting a kiss goodbye. HA. I pull away, and she stares at me in shock and disbelief and walks out.

I finish myself off, so I can think clearly, wait a few minutes, and then text her "Don't pull that shit again."

She responds which, "Whatevs."

I read it and don't answer. I have better things to do than argue.

A few minutes later she says, "I don't even know what I did wrong."

What am I supposed to say here? We've had sex 3 or 4 times now, and all she talks about is how much more dominant and "sexy" I am in bed than anyone else she's ever been with. My first reaction on this type of post would be that I am unsatisfactory in bed, but that is NOT the case here. Of that, I am 100% certain.

So what needs to be done?
