When the Internet got relatively mature, sale of any sexual service not involving a minor could be made to anyone not a minor.Once means of transmitting payment were developed, phone sex turned into primarily a commercial activity, with customers (overwhelmingly male) and sellers (overwhelmingly female).Due to the potential for emotional intimacy between those who have engaged in phone sex, it is a matter of some debate whether phone sex is to be considered infidelity when involving a person outside of a committed personal relationship.Originally phone sex services consisted of a managed network of dispatchers (live or automated) and erotic performers.Performers would come to a studio where they received a cubicle, coaching, and cash incentives to keep callers on the line longer.Typically the telephone companies would bill callers to chat lines and then remit 45% of the money collected to chat line operators.
