Damn, that's crucial. Maybe it's like swingers and swappers. Some people just have that understanding. In my 20's I used make a pretty nice hustle fuckin white chicks in front of their husbands. Be at a bar and some dude would walk up and tell me his "friend" wanted to dance with me. The "friend" ALWAYS turned out to be his SO and the guy ALWAYS wanted to see her get her guts beat out by a black guy (I never mentioned the Latin side while they were buying my drink). Haaaaaaa
But the point remains, some people have that understanding.
