Perhaps you should try a different angle. Not every black man is a Thug, Dom, or even well endowed. It is completely childish to think so. I certainly am not ignorant enough to believe that I am every woman's fantasy. I do know that with the right woman, we can make the earth move. I am selective and do no waste my time with women who are not exactly what I want, does that make me full of shit? Hardly!
Also, take a look at it from our side. How many times have we been lured by someone posing to be a white woman, when in reality it is a white man. Think that doesn't get old? Can you blame us for being cautious and wanting proof before going forward?
Anyway, good luck in finding what you want and be open enough to accept it once you get it! Success rates in this place and anywhere online for that matter is extremely low, accept it and move on.
