OK here´s what I can say:
a) GERMAN women love blacks and there is still lots of taboo attached to it. I know many German girls that since going black for the first time (usually in the US or in Africa) have NEVER come back.
A very beautiful blonde student I knew was literally passed from black boyfriend to black boyfriend - when the one was over with her, the next one was there. She was the perfect German - looooong and straight blonde hair, blue eyes, a doll. I witnessed this happening with three boyfriends in the period of maybe 10 months. She believed that they were in love with her

b) FRENCH women do the same, and in France on any given day on any given street you will see LOTS of mixed couples - black male, white female in most cases (but also many white male, black female)
I have met a Hungarian girl who had several Black boyfriends.
