How can I get my husband to stop playing with his blow up dolls and to start paying me attention again?

I was furious at him one day, so I told him that he had a small d*ck. He didn't get angry at me in turn, but acted depressed and dejected. He wouldn't have sex with me after I said that, even after I apologized. The next week, I noticed a blow up doll in our home. At first, I thought it would be best if I just ignored it, but then I noticed another and another. Three weeks later there are now five blow up dolls and we still haven't had sex. What should I do?
