i had a similiar experience in dublin with a girl who claims to be knowing portugeese. But i took it as a message from god who does not want me to get into paid sex. I am thankful it happened. It will save me loads of money and i will find another way of relaxing with a girlfriend rather than incidents like this which leave you more stressed. you think that they will help you to relax but they increase your stress levels. i will advice all to stay away from this. it is upto you if you take my advice!
Cheers!
Bye
