My ex boyfriend cheated on me with escorts, and it didn't matter that I gave him as much sex as he wanted, and out sex wasn't boring at all. I think guys who aren't single and still see escorts, do it (mostly) for the thrill of it, not because they are treated badly by their partners.....
Anyway- i have read half of the first book, and couldn't take anymore. It was so cheesy, unrealistic, yet predictible the same time. And full of cliches like: the girl putting the guy's shirt in the morning and cooking breakfast, helicopter date, 5 orgasms in 2 minutes...
