(((((((chipmunkgal)))))))) There is a group called SLAA. I believe it stands for Sex and love addicts annonymous.

Are you in therapy for yourself? this is the most important thing. Even if he does not want to change this, you can work on your own issues. Please please do not judge yourself by the standared of his addition. Having read your post, I want to tell you that I already care deeply about you. Sometimes my heart just goes out to someone. And you are one of those people.
I want to just scoop you up and hold you safely and tell you that you are enough just as you are. Good enough. Beautiful enough. When your husband speaks about sex, its more than likely he is speaking through the voice of his addiction. I would never believe words spoken through the voice of an addiction.
I hope you are getting help for you. Because you deserve that. If he is not willing to get help, then you can. Sometimes when we get help for ourselves, the other peopel begin to change. So that might be incentive to get help for you.
Sending safe hugs for you
