This!! Completely agreed. I always reveal my race along with other physical stats before meeting with an escort. If I'm paying for a service with my hard-earned $$, I want to be able to relax and enjoy the experience without having to worry about being rejected or given sub-par service due to an escort's potentially insidious, deeply sewn racial prejudices (I hate the blanket and seemingly innocuous term "preference").
Racism is unfortunately a harsh reality in our world, but I'll be damned if I allow it to put a damper on my orgasms. Self-disclosure regarding my race before meeting any $tud eliminates unnecessary doubt or worry of rejection on my end.
