From article:

The late researcher Dr Al Cooper called cybersex the “crack cocaine of sexual compulsivity”, and found the web could lure and trap people, even to the degree where they needed intensive therapy to free themselves of their addiction to internet sex. The temptation of interacting with people online, combined with the lure of feeling desired, the appeal of expressing an alter ego and the wish to escape from one’s problems in the “real” world, create an intoxicatingly addictive environment.

It’s called the triple threat: AAA: Accessibility, Affordability and Anonymity.
