So here´s what happened:
About 3 months ago I met an exchange student from Finland in my univerity (I live in mexico). I have seen her a few times at parties. At one party (Her house) I was actually very close to kissing her but I didn´t (still don´t know why). Anyway, I threw a party on Friday and it was like 5 am and not many people left. I tell her i owe her a magic trick (We´d talked about this another day). So I take her to my room, do a magic trick to her (I´m actually good), and the I do another one which involves a kiss and the cards in your mouths swap. So she was quite impressed. A few minutes later I start kissing her, and man shit escalated quickly!

Anyway, the Saurday morning she left early. She texted me almost immediately that she forgot her umbrella and her earrings. we exchanged like 3 texts in the morning.

The thing is, I really like this girl and she is leaving mexico soon. Also, I was quite drunk when we had sex so I definitely want to do it again because I wasn´t very good and can do much better.

My goal is to make her sort of my girlfriend for the time she will be here in mexico.

Should I text her today to set up a date tomorrow? on friday we talked about going eating somtime this week.

Any comment or advice is welcome! thanks in advance.
Extra info:
I´m 20
She´s HOT
She´s throwing a party in 2 weeks

Hooked up once? Your goal is to make her your girlfriend?

Dude, how experienced are you in having sex with girls?

My impression based on what you wrote is that you're thinking something along these lines:

"OMG I finally had sex with a pretty hot girl! I got so lucky! It's probably gonna be a really long time until I get the chance to have sex with anyone else this attractive, so I should try to get into a relationship with her to ensure that I can have more sex!"

If that's where you are right now, snap out of it, bro.

Have faith in the process of progress. Keep working on your skills instead of worrying about keeping any one girl around. There will be more girls. PLENTY. As long as you keep at it your results can come exponentially. Don't lock yourself into any one option out of scarcity. Abundance mentality.

You are right in your advice but I don´t think i am in the position you think I am.
I´ve been with many girls recently but this one I like.
And like I said she will be here for like 1 month only, so I want to fuck her as many times as possible before she goes.

Great!

Moving on then, why would you behave any differently from how you were behaving? Seems like the only thing you need to change is to actually see her more often. So make that happen.

There's also a pretty good reason for her to come back to your place again: those earring and the umbrella.

Amen

Just to let you know how it all went, we went out eating a few days later with the excuse of returning her her earrings.
Last friday we were texting in the morning and I told her that my roomies left me alone for the weekend and she told me she was in exactly the same situation. So I told her that she should come watch a movie to my place but she told me she was going to the movies with some friends and that I should join, I tell her no and then I text my friend (the guy that was organizing going out to the movies) and ask him to cancel her. He does so and a few minutes later she texts me saying that he canceled and that she is going to my house that night. (It was just the perfect night so I had to make it happen)

We spent almost all weekend together and I can say we have bonded extremely fast.

This is actually what I want because I want to meet a lot of women but in a deeper level so that I have a better idea of what kind of woman is for me and what kind of relationship. And our relationship is forced to end in a month.

Thanks for the advice chief I can say I really used the "seeing her more often" one

Your homie is the real MVP

I feel the same as sheikh, If I have sex with a decent girl really drunk, I really don't care about my performance. But if she is really hot, I make sure I know what I'm doing to ensure I am doing a good job in bed. If she is decent but have many hot friends, I also do my best, and I never have sex if I'm way too drunk.

I live in a low populated place, so how rumors spread, that is why=D
