We have been married for three years, he does not want to get intimate

I have been married for 3 years and my husband has completely lost interest in any type of romance or intimacy. He seems to be afraid of not satisfying me sexually, therefore avoids all closeness. He is aware of my need to be close, however I have never demanded sex. He doesn't want to discuss any solution, and frankly I'm not sure he or I know of one. This has gone on for two years. I have simply tried patience, but I am starting to doubt his love. I am positive there is no one else. He states he is just not interested in sex with anyone. The last time we were sexually active was two months ago.

My husband is 36 years old. Sex for us was great when we first started dating. Please, please what can I or what should I do? My main concern of course is to resume closeness not so much sex, although that would be nice. I just want him to feel he can be close to me again.
