Alice, I think of you and a lot of the ladies are more like therapists for some guys. There are many different reasons why people go and pay for sex. Some clients want to go and just have fun, and don't have any personal issues, but there are some that do have personal issues and need therapy, guidance, counseling or whatever you want to call it. Social work is too broad of term, like calling all physicians doctors. In medicine you have your general practitioners, but you have so many specialized medical fields now that no one doctor is an "expert" with experience in all of them. The oncologist, brain, and heart specialists want to keep up with the latest news and developments in their own field, and don't have time to read or learn about other fields in depth and become experts. I guess that is why with some medical plans, you see a primary care physician that evaluates and can refer you to a specialized physician if you need one. I think of some of the brothel courtesans the same way, different levels of expertise and different levels of involvement with different clients. Client evaluation can take time to learn for both types of professionals. Some courtesans want to be a Jill of all trades and do everything, but with many of them that have worked a long time in the business have developed their own "specialties" that they excel in.
You're very right. We do specialize in our own ways, but I feel in general and in terms of naming conventions it's good to be well rounded to a degree, and specialized. (I think this about most things in life. You should be able to cook, clean, fix your sink, repair your car, etc, at least basically, but obviously you'll be better at some things than others) So I like saying sex worker because it's generalized enough, and people know what I mean by it. My website, the reviews people write, posts, etc, those all speak to my specializations. If I used a more specialized name I feel it would either pigeonhole or confuse. People might not know what I mean by a name, or people my think just cause someone lists themselves as a kinky Domme that they can't do GFEs, or if a lady says she's a PSE specialist that she can't do outdates, etc.
