On a side note, not all African American men have huge cocks. That's really an old wives tale. I'm sure that topic would make for a vibrant discussion but it's just not true.
I would think that one of the reasons why some ladies do not see certain types of men is because of past issues or concerns about safety. Or just not wishing to deal with any more unpleasantness than we sometimes have to.
Marcus is correct, though. This topic has been discussed to death.
