is this a serious problem or am I just over thinking it? might be tmi.

I'm in a relationship with an amazing man, the man of my dreams. I never thought I would find a man like him. we are so madly crazily in love with each other. My past relationships have been nothing but abusive...sexually, physically and emotionally. My man now is nothing but good to me and we are best friends. But... I find that I don't enjoy sex with him anymore. He isn't giving me what I need sexually even though we have sex everyday. I find myself faking it a lot. He's smaller than what I'm used to and much more gentile. I just don't feel the passion, the urgency for my body. Am I crazy and just creating a problem because I'm not used to something so good? Am I so damaged that now I only see abuse as passion? What's wrong with me?
