The fact that the comment above may make people uncomfortable is perhaps the best reason to prevent it from being buried.
(For the record, and in case it makes a difference in interpretation: I am married.)
I mean, you could have asked had I read Dworkin rather than framing your remark like you are sure I haven't, which is kind of an insulting, dismissive thing to do. And, upon googling, gee, if you mean THIS Dworkin http://en.wikipedia.org/wiki/Andrea_Dworkin, then: no thanks. I happen to like men and sex, I worked hellaciously hard to get there and I am not interested in drinking deeply of her rage. Her apparent thesis -- that porn is linked to rape and violence against women -- flies in the face of statistics that internet porn apparently reduces incidence of rape and, from a quick skim of the Wikipedia page, I get the impression she was pretty angry and dissatisfied with life. I generally try to get my advice from bon vivants, not embittered cynics.
False.
The actual reality is that, when adjusted for skill and seniority, women make just as much as men.
This is one of the most malicious feminist lies out there, eclipsed only by the 1 in 3/4/5 rape lie.
So I have kind of a big problem with your idea that prostitution is per se some big moral problem here.
