For me personally, I've been married for 16 years to my husband. Now IF anything ever happened in our relationship, I would most definitely date, and perhaps marry, a black man. Since we've opened up our relationship I'm only attracted to him and black men. Can't fully explain the reasoning, maybe it's because they seem to be more self confident.
Now I wonder how many of these black men would be willing to share me with other black men if that were the case. While not in every case, I wonder how many, who love having "white married pu$$y" would share it if THEY had it?
