I am a guy that went through a very similar situation in a past relationship. When I met her, I was deep into the addiction. Even during times when our sex life was great, I still needed my fix (even sometimes just hours after I had just been with her). In my opinion punkinye, it is not other women that should be your primary concern. Your primary concern is the addiction itself. People who are affected by that are living in a fantasy world that is a lot more intriguing because you can be with any variety of woman at any time ... and they never say no to anything. I can tell you that your man more than likely has a low libido because he is STILL deep in his addiction.
The only way this can be reversed is if your man chooses to take the steps necessary to get out of the fantasy and return back to reality. When I was with my ex, I was too into the fantasy to let it go. Now I am at a point where I realize the negative impact that has on my life and I am taking the steps to get away from it. If you or your man have not done so already, check out this post:

This is what motivated me to get away from the addiction. I wish you luck.
