Men and baby talk HELP!!!?

My husband is 39 and he talks to me as if I'm a baby (my sweet little mouse, I need snuggles...) He also thinks he is funny but not many people find him so. He is obsessed about money and saving and has major probs in the bedroom. I am begining to loose my rag with him after 5 years and was wondering if there is anything psychological that can be done for him.
