My fiance and i have hit a rough spot referring to our sex lives. He never wants to do anything with me anymore. We have never been the type to have sex very often and i always assumed that was because he just wasnt that type of person. However lately we havent done anything at all. Even when i try to. So i talked about it. And he told me it was because he doesnt like to disappoint me. And he feels like hes not big enough to please me. (Hes about 5")  But i always tell him how perfect he is. And try to show him how much i enjoy my time in bed with him. His confidence is really low and i dont know what else i can do to help him bring it up. I want him to enjoy sex and not worry about his size. Because he really is good in bed. And im not ever disappointed. And i hate seeing him be so hard on himself. How do i help him build his self esteem? How to i really let him know that hell always be enough for me?
