You didn't tell us much about yourself, what your budget is, what your preferences are, your location or your language skills, so it's hard to know whom to recommend.
That being the case, I'll share the fact that the first time I visited an SP I was so nervous I locked my keys in my car. So, take your time, breathe deeply, and have a great time.
If English is your first language, my recommendation would be to start with a lady who is also fluent in English. You couldn't go wrong with Paige Adams or Avarice. I'll bet that, if you tell either one of them this is your first time, you'll get extra special treatment.
Not that there's anything wrong with Asian SPs, it's just a matter of how much you need to communicate. Of course if you're fluent in Mandarin, pick up a copy of Sing Tao Daily and go nuts.
Happy pooning!
