You need to find a different 'hobby' - 99% of working women I've ever spoken to complain thet men don't know the difference between urethra and clitoris.
And all it takes is a "you're doing it wrong" and its all sorted in that quick second.
If we need to find a different hobby then this will mean you are out of work by default. You clearly want to be out of work by saying this, it will never happen that men will quit seeing Escorts so its clear the best course of action is for you to quit.
And also you have truly spoken to 100 people on this subject of men giving oral sex wrong? where was that the Escort convention?
What did you do to that one Escort who thought guys were doing it right making up that 1%, did you kick her out?
