Nothing wrong with looking for a good time.  However, given the fairly strong LE crackdown against the hobby, it's understandable that a newbie request such as yours coming out of the blue would be met with skepticism.  Besides, it's happened before where posts like yours have been sniffed out and proved to be LE fishing for targets in the past.  Maybe you aren't LE, but until you're here for a while, be prepared for raised eyebrows.

The suggestion to get VIP status and check reviews is a helpful one.  That's the first place to start since you can narrow down your choices to the providers that meet your tastes and needs.  Then search the board for threads that may concern the providers that you are interested in to see if there are any past issues with any of them.  From there, you should be able to find a good time.  

A note in response to some posts above recommending Suzanne.  I've had the pleasure of seeing her, but even though I thought we had a good session, the next time I tried to schedule an appointment with her, she said that she felt more comfortable with guys over 35.  (Odd, I thought, since I turn 34 next month, but I respect her decision.)  She may not have remembered me and she may have been offended by the review that I posted on her (why, I'm not really sure), so be forewarned that while she is a very good provider, if you are under 35, you may not hit it off with her.

Just my $.02.
