I've heard plenty of stories about Amsterdam. I also realized that prostitution was probably legal when I saw bordello ads in Berlin that listed the various available sex acts and what they cost. (An interesting way to expand a student's vocabulary as well!)

So is Alice Schwarzer the German Andrea Dworkin? I could write a giant essay on the subject, such as mainstream influences on the porno industry and movements in alternative erotica, Yadda yadda yadda... (Don't get me started!)
