In my wife's case, it was the reverse situation. She was being hit on by young black guys when she was out at clubs or with female friends. This turned into a theme in our sex fantasies and eventually she turned that into reality. But she has said that she is attracted to black men because of the colour contrast (she is a very pale skimmed redhead) and she genuinely finds black men attractive. Then, there is also the social taboo that she finds exciting. She is more confident now and likes to be seen in public with a younger black lover and get 'those' looks from passers by. A few weeks ago she was sat in a cafe with a black lover shortly after they had made love and she held the gaze of a women at another able who was clearly intrigued. All the while she could feel his semen oozing from her vagina and into her panties. She enjoyed that a lot.
I'm pretty big and she says that she has yet to encounter one that's bigger (I think I believe her as she has no reason to lie - I'd find it a turn on if she had taken a larger one and she knows that). What I'm saying here is that it is not necessarily about size.
