Agape has got it pretty much spot on, I reckon. Don't put this girl on a pedestal. It sounds like she gave you sex unlike anything you've had before.

But, and this might shock you: we should spend time with girls for reasons other than sex. Other girls you meet will be less skilled in bed, but will be more intelligent, better to talk too, more fun, more adventurous elsewhere, have more interesting things to say, be interested in other things which are new to you, etc.

Don't just get with a girl based on how good the sex is. Look at everything a girl can offer you, and you'll discover there's so, so much more to it all than that.
