Most recovering sex addicts have spent their entire addiction trying very hard to not feel their shame by escaping into sexual fantasy and activity. Other shame avoidance coping mechanisms they may turn to include isolating, keeping secrets, people-pleasing, and being aggressive, along with compulsive drinking, drugging, gambling, spending, etc. Unfortunately, all the mechanisms that sex addicts use to avoid feelings of shame also prevent meaningful interpersonal connection, which happens to be the only proven way to abolish and destroy it.
