Relationships

I'm in a relationship that I should be happy in. Don't get me wrong I like him a lot and his a very sweet guy. The sex is ok but there is something miss. I guess its that im us to having a guy that takes charge, and tells me what I can and cannot do. Even though half of the time I don't listen. Maybe it's just that he is the complete opposite of what I normally would date. Is there something wrong with me or is this relationship just not the relationship that I was looking for? Am I over thinking what I have or is there really something missing?
