If you feel you are clumpsy with CVs, and all the excuse for wanting a SP, i'll tell you THE REASON why you should not. Just imagine you go see a SP, for whatever reason you find it unsatisfying or worse: you are turned off by the experience (happens you know: YMMV, disgusting because of the thing...) then you are really F**K big time.
The first time is special, do you want to give it to a lady of the trade?
