Weiner's Digital Flashing

Who finds fulfillment, sexual or otherwise, from a three-year series of sexually explicit electronic-only relationships that never lead to physical intimacy?

A quick thought about Rep. Anthony Weiner: if his account is true, it seems pretty obvious that he is an exhibitionist who gets off on exposing his private parts to others. What other type of man (or, for that matter, woman) would find fulfillment, sexual or otherwise, from a three-year series of sexually explicit electronic-only relationships that never lead to physical intimacy? Twenty years ago, in a world without widespread Internet, Weiner probably have stood on a street corner wearing a raincoat with nothing underneath.
