My favorites are so far the Latina girls.
You're absolutely sure you don't have to do it by yourself

The ones I met were all into the anal sex as well, even for the one night stand
The Dutch girl are not matching my personality.
It's a single shot and leave asap.
British are realy enjoying alcoholic casual sex.
I never had any sex with Turkish or Morrocan girls here in Holland.
Far too dangerous, before you know the complete family is knocking on your door insisting you marry the girl....
