The more I talk to people about sex addiction the more I've realized how few people actually know what it is. This is perfectly understandable and certainly of no fault to those people. I have also discovered how few people understand the science behind this brain disease or want to hear about it that way. I have one friend in particular who was really struggling with seeing why sex addiction is a bad thing. Here is how I explained it to him. Don't worry; there is no science involved!
