Dan admits to being a sex addict.  He would seek sex from prostitutes in New York City four nights a week.  He never had to worry about money, as Dan could hold down a job and keep enough money to spend on sex workers.  Looking back, he could see he existed mostly in an altered state; Dan got a high from seeking out a prostitute that would fit his fancy.  And he was married.  One day he wondered if he could go without buying sex, and though he tried, he could not.
