The Internet is creating a new breed of sex addict according to the latest research from the US.

At a conference on sexual addiction in California last week, researchers claimed that 15 percent of surfers have visited sex chat rooms or porn sites with almost 9 percent spending more than 11 hours per week surfing for sexually related material.

Online porn is no longer the domain of males, researchers say. An equal number of women are also getting in on the act although females generally prefer sex chat to pictures.
