life-long abstinence and you don't touch that substance again. with sex addiction, you are trying to relearn how to have sex in a way that is sane for you. it's actually fun. sex addiction ends up not being very fun. that's a misconception that you are out there having all this sex and it's a lot of fun. it's really isolating and depressing for a lot of people. >> because it's never enough? >> it's never enough. it's not really about the person. the person is a drug. that's actually not fun after a while. it's also not fun as a lot of sex addicts experience. you have to go to work at 8:00 and you want to go online and look at porn for a half hour and you are still doing it six hours later. you wonder i have all this will power in other areas of my life, why can't i stop this? it's really a very confusing problem to have.
