@magnum315 -- Kate's post (#10) above is absolutely spot on.
Visiting an escort can certainly increase your confidence and give you some pointers, but there is no substitute for a one on one experience with the woman you mention. As someone else here said, every woman is different and a technique that could drive one person wild could leave another staring at the ceiling.
You don't have to be highly experienced or super confident to give a lady pleasure. If you are both relaxed and into each other, it will happen and the chances are it will be really good. Don't rush things, be gentle and listen to what your partner's body is saying.
