There are a number of reasons why a girl on BP may say that she doesn't see black men....
1. She has a manager/pimp, and he is trying to make sure no other managers get a hold of her
2. She may indeed have a problem with "well endowed" gentlemen
3. She has had a bad experience with a black hobbyist and is protecting herself
4. She may be prejudice against AA men
When I posted on BP for a few months, I stated in my ad that i don't see black men under 40, and I did so because pimps will call and text all day and night trying to recruit girls.
There are probably several other reasons..
But like someone above me said, that thread will explain it all
Enjoy your stay on ECCIE... and welcome!
