It took me ages to find my first punt. I was as nervous as fuck and lasted half the time I'd paid for.
However, I told the wg it was my first time and she practically seduced me in making sure I got what I had paid for. I left happy and very satisfied !
If you want some advice, find a well established wg with a good reputation on here, have chat with her and tell her what you want and that its your first time. If you find the right one, she will be very understanding, then once you get into it,,, believe me, it will all go out the window and you will have the time of your life !
