The short answer is yes.  If you think about it psychologically, addiction is defined as any behavior that continues despite negative consequences.  We all know someone who has continued to have unhealthy sexual behavior despite bad things that happen to them.  If you look at it biologically, all drugs of abuse have been shown to increase a chemical called Dopamine in a part of the brain called the Reward Pathway.  Guess what causes a natural spike in Dopamine in that part of the brain...that's right SEX.

Now, that was a short and (maybe not so sweet) answer.  If you're looking for more,Sex Addiction 101: A Basic Guide to Healing from Sex, Porn, and Love Addiction, is a great place to start.

In the author's words, "The book also provides sex addicts with strategies to protect themselves from the online sexual onslaught."  It will help you understand what sex addiction is, and how to start addressing it.
