Last Saturday night, I met a girl at a party who was from a university 20 minutes away from mine on the metro. I coaxed her into leaving the party by saying I'd show her around campus, but we ended up coming back to my dorm and she later spent the night with me because the metro in my area shuts down at 2:00am. Now, I did get a blowjob out of her, which was apparently her first, and we did various other versions of fooling around, but I never got all the way because of LMR (even though we were both naked in bed), no matter how convincing I was.
We cuddled over night and fooled around a little more the next morning, which was risky because my roommate was home by then. However, she soon had to go back to her own university so she could change and go to an event, so we exchanged numbers and parted ways.
I didn't text her the next day because that would have been weird. I did, however, text her today because I'm interested in getting to know this girl better, in person as well as in bed. Here's how our conversation went:
Me: Hey, how'd your event go?
Her: Ha I never actually made it back.
Me: Haha probably my fault, sorry.
Her: Haha definitely not. Unless you've been conspiring with my professors to give me a lot of homework.
Me: No, but I can assure you our professors are conspiring together.
Her: Ridiculous. I didn't come to college to learn.
Me: Exactly. I don't need this math shit to be an engineer. I'd be better off sticking shit together and seeing what goes boom.
Her: I like it. Sounds safe and smart.
Me: Only the best at (college). It's not like we text cute girls during math class in the front row or anything.
Her: Hahahaha oh no, am I interrupting your education?
Me: Education? Psh, I though we already established that I didn't need this.
Her: Haha true. Is wasting money an added bonus?
Me: Hey, you can never pay enough to party. That slip of paper they give you means something too, apparently.
Her: At this rate I'm not even sure you'll make it to that slip of paper.

Me: But that's what makes people want to PAY me to blow shit up!
Her: Well in an interview when they ask you why you didn't graduate, just explain that you were texting cute girls during math class. They'll admire your spirit and let you blow shit up.
Me: Ha, or maybe let me BE blown up. Now, unfortunately it's a lot harder to text cuties like yourself during a chem lab, 'cause I really might blow myself up. You need to come up soon so I can actually show you around campus, because it's almost as gorgeous as you are.
Her: Still as smooth as ever. Haha enjoy actually paying attention in class.

Now, what frustrates me is that she didn't give me an answer to my date request. I'm confident that she's into me and that she wants to see me again, but I don't know how I can make the request again without coming off as clingy. Can you guys analyze this and possibly give me some advice?
Thanks!
Edit: I'm a Freshman, and I'm pretty sure she is too, by the way.
