That's why I wrote that this is my PERSONAL experience with it.
I also don't think it necessarily has anything to do with color or nationality.
But I just did the math in my head and I would say that 8 out of 10 blackies didn't bring me to orgasm or didn't want to bring me to orgasm afterwards.
With white guys, I would say it's maybe 2 out of 10.
Mind you, I am a woman who is extremely dissatisfied when a man doesn't come. And then I really do everything I can to get him to come.
Again... The figures are simply empirical values from my own experiences.
But I am a person whose eyes like to see beautiful things, I can take a lot from the interplay between the man's dark skin and my very light skin when having sex with black men. But that wasn't the question posed by the author.
