There are a few people who especially helped me out in my research for Book 2 and I offered to publicly thank them.
The last couple years I collected a number of e-mail interviews from men who see escorts. All were forthcoming in their answers and they collectively provided a great confirmation of my opinion that honest advertising/marketing is the best way to go. A lot more were expressed in the interviews; that's just a starting point.
I would like to say thank you to these men for taking the time to answer my questions. Now you finally know why I was asking those particular questions!
