Such a question involves layers of answers which are never definite. Like asking what attracts a Man to a Woman is like asking what attracts the planets to the sun.
A lot of factors are involved. One is a white woman's complexion when resting against mine. Believe me, nothing tops the cake more than that. Its the moment when really you see how marvellous God made us different and yet the same.
Another is Voice: listening to the rise & fall, timbre and laughter of a white woman's voice is quite attractive to me.
A third: Hair - no woman possesses more dynamic shades or styles of hair than they do.
Tan Lines: they look so erotic on a white woman's skin... Especially on her panties lines.
There's more, but these will do for now.
