"Some people take their daily angst and rage and not so shiny happy feelings and put them into music, or art, or poetry, or sports.  Some put it into sex.  And in such cases, I think it is far preferable and yep, more healthy that they are doing it in a controlled environment with consenting adult people.  They say art imitates life and all, and if porn is considered art, well, life isn't all roses and long walks on the beach and all."

Pleasure or relief or comfort or entertainment or anything else that one seeks out a sex worker for- all those things manifest themselves in a huge variety of ways. It is not as simple as the proper use of condoms. Sex workers are helping people experience life and helping minimize the risks that are potentially involved when novices (of all varieties) play.

Then, as Chris said, there are the elements of pleasure, communication, intimacy that sex workers are uniquely suited to educate people about.

Sex workers rock!!!
