There are counselors that are more friendly towards people with alternative lifestyles.
This is a post that I did in the legal section for someone else. I just did a cut and paste. It's pretty self explanatory.

I've been checking for some therapists that are sex worker/kink friendly and the above are two sources.
Your friend will have to do some research, but there are some therapists who will actually visit with you over the phone, if you cannot get together.
Seems smart to try to find a therapist that has SOME understanding of what we do, or is more accepting of it.
I would imagine, from the limited scope of counselors that I've run across in my lifetime (there have been enough), that plenty of them have HUGE prejudices with regard to sex work.

Hope this helps.
