Something happened the other day I can't get my head around, I've been out of the LTR game for too long. Slowly reading sidebar again.

It was late at night. Me and my LTR (new LTR of 1 week) fucked at my apartment, went out to get something to eat, and after I drove her to drop her off home (she lives with her parents/I don't want her staying over at mine, I like my space). Before I started heading to hers I said to go back to mine to fuck again, but she mentioned she was super sore from our first session and we can do it another time. I didn't push too hard as we banged for a while and she looked wrecked.

Anyway halfway to her place she mentioned about us traveling together next year and I said with a smirk "Wow, are you expecting as to be together for that long?" and she replied "yeah I am, do you think we will last?".

I smiled, said nothing, pulled over and gave her this massive kiss, then kept driving and said "maybe, but you'll have to figure that out for yourself." About three seconds later, she had this massive smile on her face, and turns around and says "I'm super horny, let's go back to yours and fuck".

I obviously take her back and fuck her brains out, but can't help but feel like she REWARDED me with sex for implying commitment or she got super turned on from implied commitment.

Is this shit normal? Should I have told her too bad fuck off I'm taking you home? I'm trying to establish a solid frame for this relationship....
