Treasure ... I understand how you feel. I have a daughter and I'd be quite upset if I found out that she was working at a mp. How upset you should be, though, may depend on why she's working there and what she's using the money for.
I know many sp's who have their heads on right, and are loving and responsible parents. Its not the job choice you or I would make, but its one they made. Frankly sometimes I wonder why they did, because every one of the ladies I see are bright, intelligent, resourceful women that you could just as easily imagine in a classroom, or a doctor's or lawyer's office. Many are actually going back to school.
Having said that, there are some girls who get into the business and get hooked on drugs. I see there being three main worries that you should have:
1) STD's ... I hope she's engaging in safe practises at all times.
2) abusive customers ... they do exist and girls can sometimes be at risk. Working at a parlour actually does increase her security somewhat. However, it may increase her exposure to worry number 3 which is
3) drugs.
At the end of the day you have to remember that she's still your daughter and the same person she has always been. Yes, doing this for a living will change her. Every life choice changes people. Whether for better or worse depends on the person and the supports they have in life. IF you're there for her, hopefully this won't be the negative experience for her that you fear. If you're not, it certainly increases the likelihood that it could be.
Don't be too judgemental. If you read through this board you will see that there is a huge range of the types of people that make use of SP and MP services. Most of us are pretty decent guys (then there's bigdee

). We use these services for a variety of reasons. Some are single guys who don't like the dating scene, or who have jobs that don't allow themselves time for dating. Others are married with kids who, for whatever reason, don't want to leave their partner and families but are sexually unsatisfied. I treat the ladies I see as if they were dear, dear friends in my life. And I know that many of the guys on this board do the same.
Similarly, the ladies stories are just as varied. I must say, though, that I haven't met a single lady in this hobby that I wouldn't hesitate to bring home to a family function. There is nothing about them that screams "WHORE". They are fine people and outside the workplace they look and act like anyone else. They're just in an occupation that mainstream society doesn't generally accept. Its hard, but try not to be too judgemental and be open to her reasons for why she does this.
At the end of the day you still want your daughter in your life.
