My relationship with my husband is going on 6 years and within the last 4 yrs he has been pushing for Anal Sex. Each time I had tried it; it has hurt not only physically but emotionally. I have asked him to stop. It's to the point when ever we try to make love he brings it up asking if we can try. I feel totally turned off from sex and he feels that I do not understand his needs. Our marriage is going down hill fast because of this one issue. He has tried to threaten me into giving him anal by saying he will find some prostitutes or with holding money to buy groceries. His obsession with it has grown so much that he surfs the web for anal porn. In his past relationships he had never had anal; so I don’t understand why he just can’t give the thought of it up. I has also have a medical condition that with my rectum that he doesn’t take for serious and thinks it’s all in my head. What can I do?
