Yeah, real world relationships with a sex worker - it's probably not like Vivian and Edward in 'Pretty Woman' with the fairy-tale ending. I know there are some "high class" high priced escort services with very well educated women, but I think it's safe to assume (OK, never safe to assume, but ...) that many/most women engaged in prostitution have a lot of problems, psychological, substance abuse, etc. It's NOT a professional of choice for most, from what I understand, but of desperation and convenience. So not a lot of stability there to start with I suspect.

No, I have not ever done that. Would I??? Well, only if I knew it were completely "safe" legally, and that isn't gonna happen in my jurisdiction. I might partake if I traveled somewhere it were legal.
