<human>: Can you give me a shortened version of the text?

A little background: she's not very sexually experienced at all. She's had only one boyfriend before me but that was years ago. I've had more experience with other women and I've never experienced or even heard of anything like this. 

We've been sleeping together for about a month now, and the first time we had sex I was quite confused. She came after a little while, about the ordinary length of time, but then she got off laid next to me. I was like "what's wrong?" and then she explained to me that once she comes, she doesn't want to have sex anymore. 

She's fine with cuddling and kissing and other affectionate things, but she's not into anything sexual. Her "refractory period" is actually quite a lot longer than a guy's, so it often leaves me unsatisfied. Soon after this, I explained to her that it's something I'm not used to, and asked her that maybe if she tried to keep going, she would get back into it. Well she tried, and she was pretending to be into it just so I could come too. I couldn't though because I could tell she wasn't into it, and what really gets me excited when it comes to sex is pleasing her. 

Once in a while she can last a good long while, and when she does the sex is really great. The best I've had. But that really feels counterintuitive though cause it seems the more passionate/better the sex is, the less chance of me being satisfied. So confusing. 

We tried longer periods of foreplay but that just makes her come faster, and doesn't really affect me as much. Also, she doesn't like giving oral so that's out too. So I'm kind of in a quagmire.
<bot>: girlfriend doesn't want to have sex after she comes, often leaves me unsatisfied. Mostly wondering if this is normal and if anyone has any suggestions?
