[Thermodynamics]

Well SS, my advice would be take things slowly, while she seems "aggressiver" in a rather cute manner now, imagine this if you blow her off in a few weeks time. From what I can gather- her being a virgin seems to tell me that she's only interested in sex when in along-term relationship. In fact, from your description of her, she definately sounds like a girlfried and not a girl for a night.

So the question is [in my opinion,] do you want a girlfriend?

Single life is fun- but so is a relationship- sum1 cool to hang out with, not to mention all those things A-sexuals don't get up to... on a regular basis, I'm sure you know how it is.

If she is so keen, play it slow, let her do the work, seem a little aloof- drives women crazy- does the same to guys, I'm sure we have all been there, that hot hot girl who you can never tell whether she really likes you or not- keep her on her toes!
