According to a friend of David Duchovny’s, there was no affair – but the reason for entering sex addiction rehab is that David is addicted to porn.

FoxNews.com is reporting that David Duchovny’s sex addiction was with online porn, equating it to a gambing addiction where he would be “trapped” in chat rooms.
