<human>: So, I've been seeing this girl for a few months. We get along incredibly well. There's no awkwardness, we don't want to leave when it's time to call it a night, we text each other about everything. Also, there's generally a lot of sexual stuff going on when we're together. High libidos. The other night she invited me over to her place to watch a few shows. After Mad Men, we start getting into it on the couch. After about twenty minutes of non-penetration stuff, she gets on top of me and starts fucking without a condom. Keep in mind that this isn't something I was prepared for, or looking for, but for some reason I went along with it. Before long, she asks if I brought any condoms. At this point it kind of hits me that she's not on the pill. I try to veer things in a different direction, toning it down a notch. After a few more minutes we go down to watch more TV. Netflix takes a very long time to buffer, so we try to start back up again. For some reason, this time I can't get hard. There's very little awkwardness, though. I just chalk it up to being tired. We watch another show, then call it a night. 
Well, that was two days ago, and she hasn't spoken to me since.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Things were going well, I get invited over and a mutual, unspoken agreement to not use a condom is made. Now we're not talking.
