My husband is a sex addicted and he dont want to see a doctor he said he is fine how can i help him .

    I think the best way is to let him know that he does have a problem and it's not right for him to carry on with his habits because they're affecting you emotionally and hurting you.  You said that he has a sex addiction, this is a very general statement and depending on which sexual acts he is addicted to, can put you in danger physically also.  But just like a drug addiction, sex addiction is similar, meaning that it progresses and will become harder and harder to overcome.  If he's addicted to pornography now, then he may start viewing it more often, letting it get in the way of his work, and it may progress into an affair, even multiple partners. 
    I think that you need to sit him down and let him know that he needs to get help for the sake of your relationship, and just let him know exactly how you feel.  Don't get angry and belittle him, but let him know that you think he has a problem, but you're willing to be there for him so that he can get better, and so will your relationship.

I think you should show him all the ways that he is a sex addict. Tell him you understand, and your not going to leave him but you do want to help him. Find him some treatment centers that could help, or even a councilor that would help, tell him you'll be there with him every step of the way but make sure you find a way for him to accept. Sex addictions can get really bad and could lead to him cheating on you, and not once but multiple times. He could put you in danger and himself. so try to get him to come forth and accept the help. I dont think you should give up and take his word for it.
