Everybody has different pain thresholds. I must say, it went a bit rough with black men in bed but only in gangbangs. I would fly home with bruised boobs from kneading and pulling, and sore holes. Real rough was it though only with my 'manager' when I was escorting back in STL. He would negotiate my workload while he fucked me before my first client or after I took the last shower. Half joking, half seriously, he would tell me I should do this many guys per day or for that much money, and if I said no he would slap my face with his cock or hand, or put his hand around my throat or deep throat me. I came every time.
