I wouldn't worry too much about the label sex addict. If you are an addict, that will be discovered through therapy. I say this mainly because the label could distract you from the real problem if you're wrong. A therapist will be the most qualified to help you find the real issues. That is, once you can open up to him or her.

Because I don't know what your husband's issue is, I'm not sure I recommend the confrontation approach. Conversation, communication, sure. But confrontation, with all the pressure that implies, could be risky if his problem is somehow connected to insecurities about himself or the emotional dynamic of the relationship.

Please don't fear full disclosure in therapy as that's the only way it works.
