This is classic sex addiction. You feel compelled, you can't go without for very long. You get angry and agitated without it.

Sexaholics Anonymous is free and it works. Look them up online and get contact info for people in your area. If there isn't a local group, you may be able to start one or just get phone numbers for other members to call and talk to. There are phone meetings as well. Get the SA white book and read through it. Then get the Alcoholics Anonymous Big Book / Blue Book and read and put into practice the steps.
