I won't go to a link that has the word "sex" in it's address (especially from work) but I was under the impression that it is legal in parts of Nevada, but not in Las Vegas specifically.
I understand, and I will tell you that it's a site for promotion of legalizing the sale of sexual favors. I had the same notion that it was already legal somewhere in Nevada. Can't find it though, and this is what I got when I tried.
