My boyfriend (at the time) was approached by a lot of the women. Some of the woman were just regular looking and we had no idea until we would talk to them. Of course many of them spoke English well. I was approached a couple of times while we were in Hamburg and I was actually quite flattered. The woman that call themselves prostitutes that I saw there were actually very attractive. Of course I did not participate in such behavior
You made a good point Yakk, sometimes you don't know until you ask!! It's not like they are carrying signs that say "I fuck for money".
