Very rare to see the "caucasian men only" disclaimer in Montreal, although I did meet an SP in Montreal who told she would not see black men because she "rejects black culture" and felt that "black men are abusive towards women." I certainly don't condone these views, but they do exist. The world is not gonna be free of racism unless we keep fucking until we are all one mongrel race.
In the last 25 years, have met many escorts who would not meet African American clients under any circumstances!
And African American are not alone in that category!
African American escorts might be so beautiful though!
