I'm guessing that you are talking about him watching pornography? If so, many women do have issues with their husbands watching pornography. I would look at your own personal boundaries, and figure out where they are. You can then determine if they are too rigid, or if they are the right balance.
I would wonder if you feel secure with your sex-life with him, and what would make it so that you feel that you have quality intimacy with him. I would look at all levels of intimacy and see if you are happy with them.
You might also look for a local counselor of therapist to help you sort this out. Whatever you do, keep communication open with your husband.
