Please don't do it
In general, these women can only be refered to as damaged goods. You must remeber that for any Sex Professional ( Stripper, Prostitute, Massage Girls, Sex Suragate, Porn Star) to be able to survive mentally, they have to be able to detach themselves easily. It is very hard to get to really know them because they are very defensive and private about their personal lives. So basically, you can not believe a word they say or project because they are so used to lying already. Remeber, 95% of the population has already voted her to be worthless scum. Unless you are in some kind of unique position where you can honestly say that you know who this person is ( and I mean that in the greater sense, not just her real name) then I would stay away from her.
Basically, she lives way outside of normal society. Are you able to deal with someone who has completely opposite view of life? Yeah, it sounds fine at first, but just wait until you actually have to deal with it. Tell me this, are you willing to date her while she still turns tricks? Are you willing to support her, financially and mentally?. The only reason women get into the profession is for the quick money. Many of them come from broken homes, or have drug addictions, or are single parents. While I can't blame their choices considering their situations, do you truely want to deal with that?
It is not so much whether or not she is a sweet or good person. There are good people everywhere. The problem is that whether she is going to let you be a part of that. And the odds say no.
