Lots of African & turkish immigrants there. White german women secretly like black american men and i say american because its just something different for them and they also looking for a way into the states. Germans are not friendly at all and they will look at you crazy at first. The women arent physically very pretty but it is what it is. There are afro germans there, african and german mix that love and somewhat mock american black culture. The mixed German women are absolutely beautiful but they struggle with how to wear their hair. I noticed this alot, Learn some German and use it while there , you will be appreciated even though if its broken german, they will respect you better. Stay in areas where there are more people and in the bigger cities. The more rural and countryside areas are very racist and they can possibly attack you and or harm you badly if you are by yourself. I also suggest try to look more like a tourist more so than an immigrant. They have hatred for immigrants of middle eastern , asian & african decent. Lots of isolated cases of immigrants being murdered there because the white german men feel like foreigners are trying to take over. Good Luck
